Within my household are two separate Amazon accounts. Neither has Prime.
My account owns a Kindle Keyboard and is
not being offered $40 off. The other account, which has no Kindle ereader or Fire associated with it, is presented with the offer. Too bad because I was ready to jump on it for
my account.
Update: When I signed back in to my Amazon account about an hour later, the $40 discount offer was there! So I will soon have a 16 GB Fire 6 delivered to my door...and now I'm a Prime member. I opted for free no-rush shipping in exchange for the $1 e-book/digital music/video credit, so it won't be in my hands until next week, but that's okay. I'm a happy camper.
Thanks for posting this offer, Fbone! I wouldn't have known about it otherwise.
