The short answer is that HEB never allows stacking of any kind -- so you can never use two coupons on a single item.
However, reader and HEB expert couponer Jennifer C. recently got clarification from corporate that we can in fact use a dollars-off purchase amount yellow coupon with manufacturer coupons in the same transaction.
The reason is basically that HEB considers these coupons (like this old $10 off $20 Garnier coupon shown in photo) to be another variation of a basket coupon, called a threshold coupon.
(Don't know what a basket coupon is? Go here for more info.)
A threshold coupon is basically any yellow coupon that says you'll save X amount of dollars once you spend Y amount on a particular brand or category of item.
So that means, if you have bought multiple items to hit your threshold on a basket coupon, that basket coupon will attach to one item, and then you can use manufacturer coupons on the other items you're buying in that same category.
Here's an example, based on the HEB basket coupon in the photo above, so you can understand what I'm talking about:
- Garnier Fructis Hair Care -- priced at $2.50 per bottle.
- Buy eight bottles for a pre-coupon price of $20.
- HEB allows one coupon to be used per item purchased. Since you are buying eight items in this scenario, you can use eight coupons!
- Give the yellow $10 off $20 HEB coupon, along with seven $2 off Garnier coupons from the 3/1 Red Plum insert.
- Get all eight bottles for FREE, plus $4 overage towards the rest of your transaction!
Remember in this sort of scenario to always give the HEB basket coupon to your cashier BEFORE any other manufacturer coupons are used. That way, you can be sure that your other coupons won't drop you below the threshold dollar amount you need in order to be able to use it.
What happens if my HEB won't combine threshold coupons with manufacturer coupons?
Like piggybacking, this combination of coupons is something that most HEB cashiers just don't come across that often -- so it's entirely possible that your cashier may try to refuse your coupon.
If that happens to you, your options depend on what makes you comfortable in the moment. You can certainly ask to speak to the manager on duty and/or store manager -- in my personal experience, I find store managers have a much broader awareness of the coupon policy than individual cashiers might.
A second option would be to follow up via phone with your store manager, or via email with HEB Customer Service, to share your experience and ask for clarification. Most of the time, HEB will email you back a letter that you can keep in your coupon binder to show at the register, and they will also follow up with the individual store.
Here's a screenshot of the email Jennifer C. received from HEB Corporate specifically authorizing this use of threshold coupons under the HEB coupon policy:
And you can always decide that combining threshold and manufacturer coupons just isn't worth the hassle -- if a deal stresses you out or it involves a store you KNOW isn't coupon-friendly, it's probably not the deal for you.
Also, keep in mind you won't be necessarily seeing HEB threshold coupons on every trip to the grocery store -- they are relatively rare, and usually available for non-food items only. But when they do unexpectedly pop up, now you know how to use them for your best advantage!
