Did not honor $0.50/gallon promo code; processed it as $0.35/gallon instead. Rejected another qualifying receipt that was submitted correctly, without explanation -- if some percentage of rebates will be rejected after nearly two weeks of processing limbo, through no fault of the user, then I don't see how the risk is worth the reward. Also, prices listed for local gas stations are frequently significantly lower than the real prices, so that advertised savings end up being net losses.
