We bought both our iPads from argos (I have a full size, DP has a mini). In my experience, it really doesn't matter where you buy an apple product from as their customer service is brilliant. We've returned a faulty iPhone that was on contract with Orange. Orange didn't want to know as it was 20 months old, apple replaced it without question. Also returned my cousins iPod which was over 2 years old and they replaced that, no questions asked. My iPad cost £400 and I would replace it in a heartbeat. One of the best things I've ever bought.
I've spent £18 on kindle pre orders today. Will probably fill the car tomorrow which will be roughly £30. Not sure if I'll do food shop after work, but if I do that'll be another £80.
