I have Sam's business card for a seven years and I am always use in it to buy stuff for my home and the business. I went yesterday to buy stuff for personal use and they told me I can't do that unless I pay by business credit card. I explain to the cashier that this that when I buy stuff for my home and it's not tax exempt I pay by debt card or cash and I been use it all over and never had problems.
Then she called a supervisor and she said the same think and she was very rude. I left a 150$ worth of stuff and went to Costco opened an account and I will spend my money there.
