BTW, for those who had your walmart orders cancelled, you can get a $10 off $15 coupon if you contact CS and tell them about your disappointment. The codes last a long time. Personally I like buying the pop secret pantry packs of popcorn which are $7.58, so I just hoard these promos (they usually last 3+ months before expiring) and then just order a few $15.16 orders of popcorn for pickup.
It's also worth noting...because I certainly didn't know this...if you use your promo code on a new order which also gets cancelled, they will refund the code and you can use it again. They don't tell you this but it works.
