If you have an Almost Perfect store near you, they have Angie's Boomchickapop popcorn at 2 for .99 cents. Checkout 51 has a $1 redemption, so I bought 6 in total and claimed 3 times. Just awaiting confirmation but it's good on any variety with no limits on the store it's purchased at.
Edit: Just got my $3 from CO51!
