The sale started this morning, it's in-store only, and according to tweets, it's crap.

A friend just popped into a store over lunch and said all stock had been reduced by 10%.
Yep, that's pretty much it. Read another tweet saying the only other discount was 20% off kitchen appliances. Everything's still cheaper online, so the only people they'll get buying things in there are people using up their gift vouchers (and the gullible ones).
