BigFishGames are holding an Endless Summer Sale! Except that it ends on the 6th of Sept 2010, so if you've seen any of their standard edition games that you like the look of then this is probably one of your last chances to get them for a cheapo price!
Recently they upped all their prices from $6.99 to $9.99 but in this sale you can get any standard edition game for only $4.99!
All their games have 1 hour trials so you even have time to try them out first, of course I would highly recommend either of the "My Kingdom for the Princess" games, as previously mentioned!
So here's the way to do it, visit the site, download a trial of a game, decide if you like it or not and if you do use the following promotional code: ENDLESS when buying it. Simples!
The only thing you can't do is buy a special edition version of a game using this code, but I've not tried any of those yet so I can't vouch for their specialness...
Of course anything you do buy helps support this site too (yay!) So it's also for a good cause!
