It is all over the place. There are at least 4 or 5 wholesalers in the UK and a some of those will be buying from a eroupean wholesaler, who buy from an Asian wholesaler, who buy from the manufacture. So you can so I can easily see why price differs so much between shops. There is most certainly some piss taking with prices but most shops need a 30 to 40% mark up from wholesale to make it worth their while selling products. I'll bet some of these prices are maybe 5% to 10% mark up just to get them out the door.
