I (unsurprisingly) caved and bought one off eBay today. 32GB plus the Apple case (which I'm selling). Should be here Thursday.
Which seller did you buy that off?
I have been checking Ebay and pretty much every apparent 'UK' seller is sneakerly faking it, and the Ipads are actually located in USA with no VAT currently paid e.t.c e.t.c
I did not find any for a worthwhile price actually located in the UK.
I would double check their ads/delivery times e.t.c to make sure if I were you.
Also contact the seller.
