Hi Jilly! I have to since losing my job and not finding another one since then. I had no problem doing it until this month when I received my Mastercard bill, my last internet purchase was done not too long after the one before and that bill ended up being more than seven hundred dollars! Thankfully I had enough money to pay that bill (a good portion of what i had set aside is gone now thanks to that) but that sure was a wake up call for me! I was far from rich but I was able to buy more freely (example...if i liked a shirt i would buy it in every colors) and mostly without looking at the price and not listening when the cashier would tell how much it was costing. Until now I have been able to always be able to pay my credit card bills fully and on time, if I can calculate more carefully I will be able to keep on doing that.
