You can get Bigfish games for 50% ($3.49 standard or $$6.98 collector's editions). This is a little different deal as you don't have to actually choose the games today. If you are a BFG Club Member you buy game credits for $3.49 (up to 24) that you can use today or in the future. If you aren't a game club member, you join for $3.49 (half the usual price & it comes with one credit) and then can buy additional credits up to a total of 24. You can cancel the game club anytime within 30 days to avoid the monthly charge. I have done this several times without any hassle. It is all online. You don't have to talk to anyone, but you do need to remember to do it. There is a link on BFG's home page that takes you to the details here.
BTW, this is a good way to get more Aveyond games or the continuation of the series whose first chapter was given away today on this site. I think BFG has them all and know they have all of Aveyond 3.
