Toilet paper at Walmart

We don't go to Walmart much but when rumours spread of them having toilet paper, I needed to know if it were true. Because of hoarders, every store in the city has been out of toilet paper for the past couple of weeks. We are down to our last few days, which has me agitated. The signs in the store indicate that there is a limit of 3 of the same item that can be returned to the store at any time. I'm surprised they would let anything be returned. They should just tell the hoarders that they are stuck with what they have and should suffer the shame.
