Is there a time limit on the Kindle trade-in 20% off credit?

[sufue]

I have an old Kindle keyboard that I gave my FIL back when. AFAICT, he never used it, and when he passed, it was still in its original box, looking totally perfect. So I brought it home, but even after several overnight tries at charging, it won't turn on. I still have a couple of other working Kindle keyboards, so I don't need this one.

So I'm thinking about trading it in for the $5 gift card (better than nothing), and the 20% off a new Kindle offer - which is what I'm really interested in, to apply to a new Kindle PW (the waterproof one). But what I want to know is, does the 20% off "credit" come with an expiration date - 60 days after trade-in, or 90-days after trade-in, or something like that? I'd probably like to get the new Kindle PW as part of the Black Friday melee, so don't want the credit to expire before then.

I get that Amazon can change the rules about whether they offer the 20% credit at all, and I'm not looking for an expiration date on the offer itself, but just whether there is an expiration date once you get the 20% credit in your account..

Whew...TIA for any help...

(P.S. I did look for a prior post about this, but it was hard to get good search terms that didn't pick up gazillions of posts. Apologies if this has been asked and answered somewhere else...)

After July 20, there may or may not be a different trade in offer with different expiration dates.
