The next best is £12.49.
I posted a deal the other day for £10.99 (£10.49 with a voucher). PPDirect put the price up to £12.49 and went out of stock within ours.
Play have it in their PS2 sale section. One of the true bargains in there since lesser known RPGs don't stay around for long, and they vanish even faster these days since the PS2 is outdated.
