I ordered from walmart online to pick up in store. It was $11.49. When I picked it up in the store today the box surprisingly came with a sticker for $5 rebate. https://apfco.com/secure/r9519w/
I followed the directions and filled out the rebate form. It asks for a picture of original cashier receipt. When you order walmart online, the in store receipt they give doesn't show the price.
2 out of the 4 retailers shown are Amazon and Pep Boys. I dont' remember the other two. I clicked on "other". I don't know if Walmart is a participating retailer.
After I went on Amazon it's listed the same price there as Walmart.
Hopefully it'll work for me
