Update: This is for anyone that ordered cups from the above post: people started receiving single sleeves instead of the 1000 cups ordered. You should complain to Amazon when you get yours to get a full refund. You can probably also get a credit for your inconvenience.
Amazon is having an insanely good deal on these Dart 12X16G Café G Foam Hot/Cold Cups, 12oz. They’re selling 1000 for just $9.78, (less than $.01 each). Shipping is free with prime, (free to join).
