We bought our shed from them a year ago, it is the first shed in my life and it's not one of those which last forever, but it's OK. We picked it either on Boxing day or the day after and they put a reduction on all outer package damaged sheds, so ours worked out at £70 including delivery.
Argos does reduced sheds around Christmass too, I can't remember exactly but I think this metal shed was on offer about £90+£20 delivery (delivery was compulsive) and it was cheaper than ebay ones.
