I recently did a DNA on amazon for $800. How long would be a good time to wait until I hit them again?

With a large $ value like that personally i've wait around 6 months minimum. I typically wait for the fiscal year to end go crazy on my aged account and then wait. I've had an account banned for too frequent refunds, I was hitting like $400 every 2 months. From my experience you can probably get away with 1200-1600 a year if you spread it out enough. I know people get away with a lot more but that usually puts your account at risk of suspension.
