It's only lame if you were planning on flipping games instead of giving your resume to Burger King. Otherwise it's fine for people who want to buy games just to play them, and $15 for $60 worth of savings a year is fine.
Some people play more games than you. If I buy 3 newer games in a month, I get a whopping 5 bucks off a 180 dollar purchase, whereas a 10 percent discount would more than pay for itself in one month. That's 18 rodeo cheeseburgers, if burger king math suits you better. :]
