I don't understand this sentiment TBH. They have A LOT of under $10 items that are very useful, and the 30% off brings them below their best coupon cost, plus many of those items never have another coupon. For example the bremen locking pliers (which are easily as quality as irwins/kobalts/husky's) and lots of their organization stuff. I have gotten a large amount of stuff withe these 30% off under $10 coupons such as their socket organizer trays, magnetic paper towel holder, moving blankets, clamps, pliers, wire brushes, and many more items. This coupon is hella useful. PLUS it can be applied to 5 items instead of the single item 20% coupons.
Second, the coupon is literally linked digitally 3 posts up and you can just show them the picture on your phone, so the idea that you have to drive home to get a paper coupon has not made sense for YEARS as they have always accepted the digital images or even just the coupon code.
