There is a coupon for $1/2 Hefty One Zip bags. These are priced at $1.25 at Safeway stores when you buy 4- so just .75 a box after coupons.
I believe these are $1 at Kroger stores right now- so just .50 after coupon!
UPDATE: I checked again tonight and I think the Safeway sale might have ended last week. I did notice that Glad Sandwich bags were priced at $2.29 at my store. I also noticed a new Cellfire coupon that popped up for $2/2 Glade bags! Combine that with the $2/2 from the Safeway MDA booklet and pay .29 per box!
Be sure to double check the sizes at your store! The coupons are for 30,40 or 50 count boxes only!

I have also found in the $1 section at cvs
The $2 Glad MFQ and the cellfire coupon are for 30, 40, or 50ct bags. The sandwich bags are 100 count. I snatched them up last night because I needed them…. and I learned the hard way 🙁 Oh well, $1.30 a box is still good for me.
Well boo. It was the same as these at my store- but there was only one box left:

Maybe they were in the wrong place on the shelf.
