Good choice. This exact scenario just bit me this month. Fortunately the bill is less than $100 but I can't even figure out where some of the charges, specifically RDS, are coming from!
Dealing with $130 in charges after the $1000 was used up because they sent absolutely no notification that the credits were almost gone. Didn't find out until the charge appeared on my card.
Genuinely curious if this has been done, but considering that a $1000 is not a lot of money which suggests you are not running a big operation, why not use it and tie the rest to a card with a limit such as from privacy.com? Granted Amazon might deny such cards, in which case, if you really want it, you can set up a new debit card whose account has say a maximum you can spend?
Why doesn't amazon just let you know?
Just because you can't actually pay it doesn't meant they won't bill you for it. That's just going to generate a debt to Amazon once the money runs out. It won't magically turn off your AWS charges...unfortunately.
I’ve had the card I use for AWS expire in the past, so I’ve got the billing notifications from them. Basically they start emailing you as soon as the charge fails and give you a couple months before they shut off your services. As long as you pay the past due charges by then, there are no complications. Based on the wording in the emails, it seems like they will just shut down the account if you don’t pay the past due charges. Which feels like the right outcome to me. I suppose they could send you to collections but companies that do that tend to be more upfront about it.
I'm more concerned about my account. Will they terminate my Amazon & prime account? Would they send it to collections and mess up my credit? I don't have the time or emotional energy to sort through that sort of mess.
Mind sharing the credit if you dont plan to use it :P
