So I need to buy a new roof, and it's going to cost 10k. The roofer will let me pay by CC if I eat the 2% convenience fee. The question is whether this is worth it or not, and if so, which card do I put it on. I fly out of WAS mostly, so United miles have the most value to me. I could use a BA card and make a big headstart on a companion ticket, but with a small child, I'm not sure Europe is in our immediate plans.

Speaking of which, she's off to private school next year at a cost of 20k. They will let me pay that by CC too, same deal, if I eat the the 2%. So this may be an ongoing question.....

Thanks!
