This offer is only for those with a Kindle with Special Offers:
Save $15 off a $30 purchase of School Supplies from Amazon.com
Click on offer, then click on the link on the offer page to receive an email with the promotion code. Sign-up for this offer expires on August 12.
You'll get an email (right away), a link to the Special Offer page and a promotion code to enter at checkout. Once you have the promotional code, you have until September 12 to complete your purchase. Like previous offers, this one requires you to use the full checkout process in order to enter your promotional code. Also, like all Amazon sales that use promotional codes, if you have a gift card balance, you must use it for the payment (if there is not a sufficient balance, then you can pick which credit card or other payment to use).
This offer can be used more than once per account, so long as you have more than one KSO registered. Just click on the ad on each device to receive the individual promotion codes via email.
I just looked thru some of the items on this offer and there may be a few items that are only for school kids, but most of it is items that I would use at home or the office, including pens, sharpies, dry erase markers, mailing labels, etc. There are even disposable fountain pens!
