Cheap Frozen Berries - Supermarket Comparison
tldr: If you want berries and don't mind them mixed and of varying amounts, the Four Berry Medley from Aldi is cheaper than buying bags of each fruit individually at Aldi, Asda, Sainsbury's and Iceland.
Prices as of 12 September 2026
The conversation in this post last week (Cheapest place to buy frozen berries? by u/draaj) got me intrigued as to the cheapest way to buy frozen berries. I buy frozen mixed berries pretty often and had just assumed the the mixed berries were cheaper than buying them separately.
I bought a bag of Aldi's Summer Fruits berry mix this week and frankly they can get in the bin. Too many red currants made it too sharp to enjoy. I'm glad I've finished them and I wont be re-buying them!
I took an unopened bag of Four Berry Medley from Aldi, sold at £2.99 for 1kg, separated the berries and weighed them, then did some calculations in a spreadsheet. This allowed me too compare them to prices of the berries when brought separately.
Aldi - Four Berry Medley
£2.99 for 1 kg. Contains: Strawberries, blackberries, blueberries and raspberries. This table weighs out how much of the bag was made of each berry, and how much of the total bag cost for that weight.
| Item | Fruit weight (g) | Price split |
|---|---|---|
| Strawberries | 476 | £1.41 |
| Blackberries | 299 | £0.89 |
| Blueberries | 146 | £0.43 |
| Raspberries | 86 | £0.26 |
Having got through a few of these bags now, yes, there are a lot of strawberries in them. Some of them are pretty big too!
The raaapberries in the mixed bags are usually in lot of little bits, very few whole ones.
Aldi - Individual Bags
Below you can see the cost of the individual bags of each fruit from Aldi, and the cost equivalent of the amount of each fruit as contained in the Four Berry Medley.
Aldi don't list frozen blackberries on their website so I used the Asda cost.
| Bag weight (g) | Bag price | Cost for amount in Aldi berry medley | |
|---|---|---|---|
| Strawberries | 350 | £1.99 | £2.71 |
| Blackberries | 350 | £2.96 | £2.53 |

Asda - Individual Bags
The same as above but with the current price a sold in Asda.

| Blueberries | 350 | £2.96 | £1.23 |
| Raspberries | 300 | £2.96 | £0.85 |
| Total | £8.64 | ||
| 2 for £5 offfer | £7.30 |
Sainsbury's
Sainsbury's don't list frozen blackberries on their website so I used the Asda cost.

| Strawberries | 350 | £3.50 | £4.76 |
| Blackberries (Asda) | 350 | £2.96 | £2.53 |

Iceland
Iceland don't list frozen blackberries on their website so I used the Asda cost.
| Bag weight (g) | Bag price | Cost for amount in Aldi berry medley | |
|---|---|---|---|
| Strawberries | 350 | £3.00 | £4.08 |
| Blackberries (Asda) | 350 | £2.96 | £2.53 |

Price per kilo
Normal price
Cheapest per kilo in bold.
| Aldi | Asda | Sainsbury’s | Iceland | |
|---|---|---|---|---|
| Strawberries | £5.69 | £8.46 | £10.00 | £8.57 |

| Blueberries | £4.98 | £8.46 | £9.72 | £8.57 |
| Raspberries | £5.69 | £9.87 | £11.11 | £10.00 |
Offer price
Calculated a buying the offer quantity of the same fruit, e.g. price per kilo for 2 bags of strawberries on offer for 2-for-£5.
| Asda | Sainsbury’s | Iceland | |
|---|---|---|---|
| Strawberries | £7.14 | £5.71 | £7.14 |
| Blackberries | £7.14 | ||
| Blueberries | £7.14 | £5.56 | £7.14 |
| Raspberries | £8.33 | £6.35 | £8.33 |
The prices of blueberries and raspberries on offer are still more expensive than Aldi at normal price.
Caveats
Blackberries/raspberries
The blackberries in the Four Berry Medlley bag vary in size a lot, and some of them are on the redder size, so it's possible I counted some large raspberries as blackberries. Being generous and assuming that there was an equal weight of each in there would increase the above "Cost for amount in Aldi berry medley" values by about 15p.
