I am sure shops have just doubled the prices of many things so they can put them on offer at the price they should always be.
Pringles are another product that now has a ridiculous rrp and is forever on sale half price for about £1.30.

​I'm meant b&h bargains...although I wouldn't mind if h&m sold them

Yeah, you can stick them to their close to improve the way they look....and taste.

same at co-op + 10% nus

This is a routine offer from Tesco, happens every 6 or so weeks. As a side note Iceland always sell them for £1 as well some H&M and the like.

4 for £3 mix and match Doritos and dips in Morrisons.

This is what the usual price should be.

The dips also £1
