as parts manager of a large ford dealership, i buy a lot. i pay for as much as i can with the card. supplies from sams club, parts from other dealerships out of state, tools, even let other employees use the card to hide xmas gift purchases. one rule, i get paid in cash before you order or if for work, i get paid in two days. yes, credit card bill is EXTREMELY high, but by banking immediately, i even earn a little(very) interest. it probably is not the best card, i saw a few months ago someone had posted a 5% earnback, but when i contacted the poster, they never got back to me. i figured it was just someone with time on their hands. anyone have a better card, please post details.
