I doubt it. Other stores just can't compete with jersey store prices. Jersey stores haven't been round for ages and prices didn't go down when they started.
I'm not saying it's a bad thing. Just it would be nice if stores actually in the UK could offer these prices.
Theres a shop I cant mention that if you order before 5 pm you get the game the next morning for free delivery. I'm pretty sure they aren't jersey based. They are almost always the cheapest and will price match if they can.

I pretty much always use that site even if they are a pound or two dearer on a game because they openly have a forum where you can highlight places that are cheaper. For me thats a place confident in their pricing/delivery and customer service.
