Based on a GCB of $0.00 at this time, I apparently did not buy ebooks from Amazon in the relevant time period.
I got over $100 from this and I buy a lot of books. Enough that I don’t know the actual number. I have a couple 100 books on my Kindle and I have had it for about 4 years.
Well, as the saying goes, “the house always wins.” My Kindle Fire started acting up, so I used some of the money to snag a new one. I’ve been wanting one anyway, since you can add a memory card to the new ones and store seasons worth of vid. Had a ‘d’oh’ moment, though - went with the 8GB model figuring the extra space would cover everything then found out books will only use the native storage space, not the card. A 400 titles currently, it’s not an issue yet but…
I got $75.20 from Barnes and Nobel. I’m doing all right with the Nook, I bought the first one ever made, and 10 minutes before the warrantee expired it broke, and they upgraded me to the Nook HDPlus for free.
