I am curious are there and apps that give you rebates for something you already purchased? I know Ibotta you select the item first, then submit receipt.
Ex: I purchased items on Amazon last week, without using Ibotta or Ebates…Is there anyway to still get rebates for these purchases?
I, personally, like Receipt Hog. They take almost every receipt and turn it into points which eventually turn into cash. It also is fun because there is a slot machine and prize drawings.
Like @jeff said you could try Paribus. I believe it did work on an Amazon purchase I made, but that was a while ago. I am not sure if it would work retroactively though.
