Anyone ever overpaid their credit card before a large purchase?
This year is the first year that you can pay your UK tax using a credit card, for a small fee.
My tax bill is literally 15 times the limit on my BMI credit card. I am planning to put my BMI credit card (issued by MBNA) into credit by making a massive payment to MBNA, and then immediately paying my tax bill. MBNA has confirmed that I can do this.
My only concern is that I may not get the miles for the tax payment (it IS treated as a purchase, not a cash advance) because I am paying it from a credit balance and not actually using MBNA's money. The terms & conditions of my card don't mention miles once, yet alone how they would treat this situation!
Does anyone have experience of successfully getting miles from using a credit card when you have put it into credit beforehand?
