Wow, didn't realize people were still doing MyPoints!
Sadly, I don't have a Walmart near me to take advantage of the deals, but I do them when I can.
I also noticed that a lot of the deals cross over to other apps, like Ibotta or Checkpoints (e.g., if you get points for buying Rayovac batteries at Walmart, Ibotta and/or Checkpoints, Shopkick, etc. probably also have that offer). Have yet to see if a receipt can be recycled.
