I ordered my non-XL through CarphoneWarehouse (in the UK). They were offering delivery before Google were offering to dispatch, all other aspects of the deal the same (unlocked, same price, Home Mini thrown in), so it made sense.
(Had I been buying an XL they were also offering the Panda for delivery in November when Google had been out of stock for several days. Guess most people went straight to Google and didn't consider that there were options).
