One thing to bear in mind about play.com (as I discovered last week) is that they appear to have gone down the Amazon route of having third-party traders selling from their website. I ordered a micro SD card and a M2 card last week and although it
appeared that I was ordering them both from Play, in fact I wasn't. The M2 card came 2 days after the SD card and has a "PlayTrade" receipt/invoice, not a Play invoice.
This is enough for me to stop using them as I won't use Amazon for the same reason (although Amazon are at least clear about third-party traders these days).
Caveat emptor as always
