Just checked my statement - charged me the $.01 price, although I was smart enough to add some other stuff.
I ALWAYS have to check my CC statements for mistakes from staples.com. Give them a call, and see if they will fix it. If not, then try the Staples Headquarters complaint telephone # is 1 800 338 0252 Ext: 2531022. I have to believe they will make it right, one way or another.
