It seems like just yesterday we posted the best of the Valentine’s Day sales. (In fact it was last week). But iOS game developers don’t pass up a chance to put their games on sale, and this time it’s Presidents Day that they’re celebrating. Read on to find our picks for the best free and $0.99 weekend game sales. We’d particularly like to point out that both Grand Theft Auto 3 and Grand Theft Auto: Chinatown Wars HD are on sale for $0.99. Just saying.
