FAQ
Which is cheaper: 500 g for 100 or 1 kg for 180?
Per 100 g, 500 g for 100 costs 20 and 1 kg for 180 costs 18, so the 1 kg pack is the better value.
Can I compare a product in g with one in ml?
No. Weight and volume are not converted because the relation differs from product to product. Compare products with the same kind of unit.
What is "Items in the pack" for?
For packs such as 3 × 200 g, the unit price is calculated from the total (600 g).
