I have just ordered a Macbook from Apple, and was planning on getting some extra RAM for it, the cheapest place is welovemacs.com (link to RAM here) which will cost £125 +tax, the cheapest I can get it in the UK is from 😱 PC World 😱 for £160, though it is difficult to get to a store as I am carless atm. is it worth saving the extra money?
