At least you know now. I bought like $200 worth of Totino's pizza rolls during a promotion to get a enough points for like a $70 PSN card but when I went to redeem it, I found out that the points expired 3 days prior. No warning or anything. I called customer support but 3 weeks later, they told me they can't give the points back because the promotion stated they expire 3 months after redeeming so I lost out and bought all those Totino's for nothing. I had no idea they would expire because I failed to read all the stuff at the bottom. I mean, they taste okay but I only bought so many of them because of the promotion. At least your purchase wasn't anything close to $200 and didn't clog up your freezer.
My question is going to come off as if I'm being an ass, which genuinely isn't my intent, but I'm going to apologize in advance anyway.
Why did you spend $200 in an attempt to get $70? Was there something else involved in the promotion that made that worthwhile?
