I have spent hundreds of dollars at costco when my mom and I go. She always shows her card and we have never had a problem with the Costco on 44th street and Thomas. I went to pick up a graduation present at the costco near Paradise Valley Mall and was spending another 130.00. At time of purchase we were asked for the membership card which was shown and I went to pay for the item and we were refused tender. I was told that I could not purchase the item my mother had to... OR I could go get cash and hand it to my mom who in turn could hand it to the employee. Really funny because it's the same dang thing. I will no longer be a spending a dime in a store who sells to people on welfare which is covered from my hard work and taken out of my taxes when they refuse refuse service to the person who's entire family are members. Bye bye costco... I may only be one fish in the sea of your members but guaranteed if I experienced this poor service someone else will as well.
