Yup, in fact the games in the OP aren't that badly priced. I only looked on the rainforest and they were a couple of quid cheaper at best, which is evened out by the fact that most of us get free next day delivery anyway. Halo Reach is a bit pricey though, you can get that £10-£15 new at most places so that's a bit disappointing. I'd definitely consider ordering with OcUK in the future if they can keep these new releases within £2-£3 of other stores.
that's what I'm trying to do. whilst some of our older stock may be a bit highly priced, anything I am buying will be as aggressively priced as I can make it.
