Are multipacks cheaper? Usually, yes: most multipacks cost less per item than buying the same product singly. But not always. Some multipacks are priced at exactly the single price multiplied up, and now and then a bigger pack costs more per item than a smaller one. The only reliable way to know is to work out the price per item (or per 100g or 100ml) and compare.
The good news is that this takes about ten seconds on a phone calculator. Below, we walk through why multipacks tend to be cheaper, when they aren't, and real examples from toothpaste and haircare, including a couple from our own range where the multipack isn't the bargain it looks.
Are multipacks cheaper? The short answer
When you compare a multipack with singles, there are three possible outcomes:
- Cheaper per item. The most common result, and the whole point of a multipack.
- The same per item. The multipack is simply several singles in one box. Handy, but no saving.
- Dearer per item. Rarer, but it happens, for example when a big "stock-up" pack is compared with a mid-sized one.
So the honest answer is "usually, but check". A multipack is only a deal if the price per item is lower and you'll use everything in it.
Why multipacks are often cheaper
There are a few everyday reasons sellers can charge less per item in a multipack:
- Less handling per item. Picking, packing and sending one parcel of six costs less per tube than sending six separate parcels.
- Less packaging per item. One outer box instead of several.
- A bigger basket. Sellers are often happy to take a smaller margin on each item in return for a larger order.
For you, the saving adds up fastest on things you use every day. It's the same reasoning behind why PoundMart sells in value bundles.
What makes a good multipack buy?
Some products suit bulk buying far better than others. The best candidates tick most of these boxes:
- Used every day by more than one person, so the pack gets finished steadily.
- A long shelf life, so there's no rush to use it up.
- Compact, so a stock of them doesn't take over the bathroom.
- Already a favourite, so you know it'll get used.
For most households, toothpaste, shampoo and conditioner tick most of these boxes. The weaker candidates are products you're trying for the first time, anything with a short shelf life, and items only one person in the house uses occasionally.
When multipacks are not cheaper
Here's where it pays to be a little sceptical, even with our own products.
Same price, just more of it
When we checked in September 2026, the Nice Smile Feelin' Grape pack of 2 was £14.90, exactly two single tubes at £7.45. The Yummy Gummy pack of 2 was the same story: £19.98, or two singles at £9.99. These packs are about convenience rather than saving.
The bigger pack costs more per item
This one surprises people. Here are three listings for XHC Argan Oil Shampoo, all in 300ml bottles:
| Pack | Price | Per bottle |
|---|---|---|
| Twin pack (2 × 300ml) | £9.99 | £5.00 |
| 3 pack (3 × 300ml) | £12.99 | £4.33 |
| Stock-up (6 × 300ml) | £28.47 | £4.75 |
At those prices, two 3 packs (£25.98) cost less than the 6 bottle stock-up (£28.47), and you'd get six bottles either way. The biggest pack isn't automatically the best value.
A single on offer
A single on a short-term promotion can undercut a multipack's price per item. If you're shopping in a sale, redo the maths at the sale price.
Waste wipes out the saving
A multipack you don't finish isn't cheaper. If half of it passes its expiry date or gets lost at the back of a cupboard, the real cost of each item you actually use goes up. Our guide to whether toothpaste expires is worth a read before you stock up.
Real examples: toothpaste multipacks compared
Here's the Nice Smile range side by side, using prices from when we checked in September 2026. Every tube is 60g, so the price per tube is a fair comparison.
| Nice Smile option | Price | Per tube | Per 100g |
|---|---|---|---|
| Feelin' Grape, single | £7.45 | £7.45 | £12.42 |
| Watermelon Fresh, single | £7.95 | £7.95 | £13.25 |
| Candy Clean, single | £9.99 | £9.99 | £16.65 |
| Candy Clean, pack of 4 | £27.96 | £6.99 | £11.65 |
| 3 Pack (Watermelon, Grape, Peach) | £12.99 | £4.33 | £7.22 |
| 6 Pack (Berry, Gummy, Candy) | £19.99 | £3.33 | £5.55 |
| 6 Pack (All Flavours) | £21.99 | £3.66 | £6.11 |
| 12 Pack | £24.95 | £2.08 | £3.47 |
The pattern is clear. Across most of the range, the price per tube falls as the pack grows, and the 12 pack comes in at around a quarter of the price of a single tube. The Candy Clean pack of 4 saves £3.00 a tube against the single, or £12.00 across the pack.
6 pack or 12 pack: which is better value?
On price per tube, the 12 pack wins comfortably: £2.08 against £3.33 to £3.66 for the 6 packs. But value isn't only about price.
Choose the Nice Smile 12 Pack if you're buying for a family or a shared house, you already know which flavours go down well, and you have room to store twelve tubes. You get four each of Watermelon Fresh, Feelin' Grape and Peachy Clean.
Choose a 6 pack if you want more variety or fewer tubes. The All Flavours 6 pack covers Watermelon Fresh, Feelin' Grape, Peachy Clean, Berry Burst, Yummy Gummy and Candy Clean, which makes it a good way to find a favourite before committing to a bigger bundle. The Berry, Gummy and Candy 6 pack suits sweeter tastes and was the cheaper of the two per tube.
All of them are 60g fluoride toothpastes described as whitening, vegan and enamel-safe. The compact tubes also split nicely between the bathroom, the gym bag and a holiday wash bag.
A quick checklist before you buy a multipack
Run through this before anything goes in your basket:
- Find the price per item. Divide the pack price by the number of items.
- Compare like with like. If sizes differ, compare per 100g or per 100ml instead. Our guide on how to read unit prices shows you how.
- Check every pack size. A mid-sized pack can beat the biggest one.
- Check the dates. Make sure you'll use everything before it expires.
- Be honest about variety. Will everyone actually use every flavour or scent?
- Check your storage space. A multipack you can't store neatly is a multipack you'll forget about.
The bottom line
Multipacks are usually cheaper per item, and for everyday essentials like toothpaste and shampoo they're one of the easiest ways to trim your shopping bill. But "usually" isn't "always". Some multipacks are just singles in a box, and occasionally the biggest pack isn't the best value. Check the price per item, buy what you'll use, and you'll never overpay for bulk.
At PoundMart, we'd rather you pick the right bundle than the biggest one. You can compare every pack size in our bundles collection.
Frequently asked questions
Are multipacks always cheaper than buying singles?
No. Most multipacks cost less per item, but some are priced at exactly the single price multiplied up, and a single on promotion can occasionally beat a multipack. Divide the pack price by the number of items to check.
Is it cheaper to buy toothpaste in bulk?
Usually. Across the Nice Smile range, the price per tube fell from £7.45 or more for a single to £2.08 in the 12 pack when we checked in September 2026. Just make sure you'll use the tubes before their expiry date.
Is the biggest pack always the best value?
Not necessarily. When we checked, two 3 packs of XHC Argan Oil Shampoo cost less than the 6 bottle stock-up for the same number of bottles. Compare the price per item across every pack size, not just the biggest and the smallest.
How do I compare multipacks with different sized items?
Use a common unit such as price per 100g or per 100ml. Divide the price by the total weight or volume, then multiply by 100. That lets you compare, say, a pack of three 300ml bottles fairly against a single 500ml bottle.
Why do some multipacks cost the same as singles?
Sometimes a multipack exists for convenience rather than price: it saves you ordering the same item twice, or makes a neat gift. Whatever the reason, the per-item maths tells you whether you're saving. If the multipack costs exactly the single price multiplied up, buy whichever quantity suits you best.
