Play-Asia have a sale on at the moment. 25% off everything in stock.
One of the best deals (in my opinion) is Chrono Cross for $24.90 US dollars. That's about £12.50 in UK money, a pretty good price for a game that never came out in this country. It's the sequel to Chrono Trigger which is a really good RPG, and Chrono Trigger is being ported to the Nintendo DS later this year. :D
Oh and hurry since there's only about a day left of the sale.
