I picked up a bargain the other day. I bought the same Final Fantasy XIII A1 Rare Poster from this seller for £3.20 + £4.00 delivery when he listed it from 99p and I won it in 3 bids.
I guess he felt it was too much of a bargain so he has increased it, starting at £7.00 and £6.00 for delivery or £20.00 for buy it now.
Admittedly, it did have a small crease in one of the corners but likely to be damaged during transit. He supplied a poster tube and included bubble wrap on either side as well as some in the middle to keep it from rolling around. Unfortunately it didn't have the lid on either side of the tube so he used brown tape to cover the ends. :/
Please note this is A1 size and is double-sided with the same image, he didn't mention it in his auction but I think is a bonus.
Here's the link if you're interested in getting one from the same guy:
