I have been charging, paying, charging, paying, etc. and on Valentine's day, I decided to test my limit to see what would happen. I had a balance of $150 and I charged $100 and the charge wasn't automatically declined! A receipt printed out for the cashier to call customer service. After he spoke w/ customer service and verified my DL w/ them (they didn't even ask to speak w/ me or anything) he hung up, typed in some numbers and my charge was approved. Just now (after reading RichGuy's post), I called Macy's to see what my limit was (every time I call, the automated response never tells me my limit) and the rep stated that my limit was now $500!!!!!!!! She stated that when I made that last purchase, they raised my limit to $500 so that the transaction would go through and that I could continue to shop!!!!!!!! Talk amazing... I just thought I would share that with you all!
