You crazy...Game fly pays for its self a 10x times over . You spend (waste) more money going the route you take. Keep banking on getting $40 in trade in deals lol.
Gamefly cost less than buying games but at the same time for someone like me it's an inconvenience. I work full time and mostly game on the weekends and even then not consistently. I can go several weeks not playing anything. Paying that monthly sub for Gamefly is a total waste to me because I could go a month playing nothing at all. Gamefly is only a value to people who game a lot, game consistently, and have a lot of free time to play.
maybe 4 years ago I did Gamefly and the turn around was 4-5 days to get a different game and they actually had to have the game you wanted or you'd get something else. You'd burn close to half the month in mailing time for the one at a time plan and the two at a time plan wasn't worth it because splitting playtime between two games slows you down on beating either of them.
I've reached a point where I no longer trade games in that I played and enjoyed anyway. The type of games I trade in are games like Madden, Call of Duty, and Battlefield. If I buy a game like The Last of Us I keep that so a year or two later I can periodically replay it. I collect good games.
