Would anyone ever accept Amazon gift cards as a form of partial payment? If they were sent in advance so that you could ensure that they are valid?

I do. Love Amazon

Next to cash, best thing around..

I shop there a lot

They are great for deposits and paying for travel dates.
Gifts and thank you's.

I've been taking Amazon gift cards as full payment for a couple years if requested. But of course there is a convenience fee, or should I say inconvenience? There's always things that I need from there for my house, gifts, Work etc  so I've always been happy to except them. I am so excited to be starting credit card payment in the next month though

Of course the payment has to clear for first (since you can use your credit card on these sites).

I happily do.

Love them, but cash even more

Cash is King, but Amazon GCs are a close second. They are very handy, though!
