Why these prices are comparable

Every offer on this page is joined on the same checksum-valid barcode (04718017755535), not on a similar name. A 1.2 kg bag is never compared with a 3 kg bag, and a refill is never compared with the bottle.

What ASAP does not do

We never hide a retailer because they pay us nothing, and the lowest price on this barcode is always shown at the top of this page regardless of who it belongs to. Within the list above, retailers we can earn a commission from are grouped first — each group is still ordered strictly by price.
