I can best that. Last year I had a GC doing a remodel/ remediation on a property (paid by insurance). Their office sent me the invoice with an online payment option, and I was happy to pay the $65k bill with my CC. Had to call the bank ahead of time to make sure there would be no issues..... it was over my limit but they said no problem.
I get 2.625% cash back on every purchase, no limit, so was happy to take a free $1,700. Couldn't believe the GC would take a credit card for that amount. Clearly we were paying them too much
