It's the little things that will make you crazy...

I was pretty excited because my new potato ricer finally came and I was going to learn how to make gnocchi. I went to Wal-Mart this morning to grocery shop and THEY HAVE NO POTATOES. I'm not saying they only had red potatoes and I needed Idaho. I'm saying they had NO potatoes for sale. How can this be? And why are they doing this to me?
