Amazon Local has a deal today (Saturday June 30th) where you can get a free voucher that will be good for 30% off of Kindle Accessories (up to $30). You have until July 10th to use the voucher.
I tried and it appears that you cannot use the voucher on refurbished or used kindle accessories. So you might want to check the refurbished accessory store first. It might be cheaper to buy refurbished instead of using the voucher.
The only thing I am really thinking about (since I don’t really like cases in general on my electronics) is the lighted cover. It is normally $59.99. 30% off is $18. So it would still be $42. The refurbished cover that is “Like New” is $35.14. Since I have Amazon Prime, the shipping would be free on both.
But you can get covers, reading lights, chargers or stylus (the chargers and stylus would work for other devices beside just Kindles.)
