My First Offer, so be gentle = )
As some of you may know, hmv currently have a buy one get one free on selected titles believe this offer is also on the website
I went into the preston store today, and saw one of the blue buy one get one free stickers on Mass Effect which was actually the only game i wanted to buy. So i took that and gears of war over to the till (both are priced at 49.99) and it went through fine.
I also got a 10% student discount so the effective price for each game was about £22.49, which is a bargain if you ask me =)
Not sure if it'll be the same in all HMV's, but worth a look!
