This offer is only for those with a Kindle with Special Offers (but the sweepstakes above is open to all):
Save an Extra 50% on Back-to-School Groceries at 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 24.
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 24 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.
Even if you don't take advantage of this deal, be sure to enter the Back to School Sweepstakes at Amazon - the top prize is a $1,000 Amazon Gift Card, which you could use for pretty much anything at Amazon.
This is a great promotion! You get 50% off your entire order and can choose from anything on the Back to School grocery page that is sold by Amazon. You get one offer per device, which means entire orders (not just single items). Order some now, sample what you like, then place another order near the end of the time period, if you have more than one KSO. You could also get an order for home and one drop-shipped to your student living on campus (or sent to a shut-in relative). There is even an extensive gluten-free section (yay!) with dried fruit, snack bars, rice bowls, Mac & Cheese dinners and even hummus and rice cracker meals for on-the-go convenience (be careful in this section, as the "gluten-free" tag kept dropping off my search as I changed pages, resulting in many non-gf products being shown; on the other hand, there are many gluten free items that are not tagged as GF, so you will want to look at the entire list).
Some items have additional coupon codes, so pay close attention while shopping (I even ran into one that had a personal $1 off coupon for me), as you can enter most of those coupon codes first, then the 50% off promo code from this offer. You can't combine this particular deal with the 15% Subscribe and Save, but you should still be able to score a number of great deals on this one. I just saved over 60% on items we eat all the time (and usually get from Amazon anyway); this one coupon code can more than make up the entire cost of a KSO (plus a lot more, if you are a big shopper). Don't forget to add in all the per-item coupon codes and your $5 off $10 Amazon KSO offer code, if you have one.
Update: Just wanted to let you know that I have confirmed that you get 50% off with the promotion code PLUS any other promotional discounts that you enter (plus those $1 coupons that I happened to hit; those are randomly given out, but you might run into one). Also, you can place as large an order as you want (and order multiple quantities of items you use a lot and that keep well); since the promotion code can only be used once, be sure to make it count (and thanks to those to click-thru to Amazon from here, before filling their cart!). I even found doggie treats (from FunBites) that qualified; you can get breakfast cereal, coffee, splenda (plain or flavored) and a pretty wide variety of things that I would not have thought of as "back to school" (which brings to mind snacks and lunches to go) and which are not specific (or appropriate) for kids. There are also big bags of various hard candies, breath mints, gums ad more (about 1,500 items in all, that are sold by Amazon.com - here's a shortcut to the entire list).
