I am stunned I haven't seen this anywhere, unless I am totally missing things:
I saw that Slurpee.com is having an Xbox One give-away, similar to the Mountain Dew give away. It costs slurpee points to enter, and you can enter 5 times per day. In addition to the entries, they also have rewards you can buy (not a sweepstakes, but the actual products). They had Xbox-live 1 year subscription card (again not a sweepstakes to try to win it, but the actual card) for 100 slurpee points, which you'd say ok for slurpee.com that is pretty decent (It would take about 30 large slurpees to get that. But here is the thing...they have 1600 point cards for 15 slurpee points (again, not a sweepstakes, but the actual card in the mail guaranteed). That is about 4 large slurpees (I think that is less than $8 total), and you get a 1600 point card. According to Microsoft's website, the pointcards still work even though the transition has occured to real money. For about 3 years, I've been banking slurpee points from my family, and we had about 180 points. I've never found anything remotely worth using on the slurpee points and figured I never would. I just cashed them in for 11 different 1600 microsoft points cards.
It seems to good to be true, and my confirmations (got 11 different e-mail confirmations) that my card would arrive in the mail in 4 to 6 weeks) just make me worry that they will pull a Walmart and cancel the offer, or there is something I am missing. But considering I never cashed in points before, and didn't really ever expect to cash them in, this could be a steal!
