Tesco also sell these crisps, though they are £1.85, or buy one get one free.

They're also confirmed on the double the difference thread, so if you buy them individually from tesco, input your receipt, you would get a voucher back for £1.70 meaning that your crisps will only cost you 15p. You would need to buy them individually to get any money back this way though, as 2 packs for £1.85 is obviously cheaper than Asda's 2 for £2.
