I rely on various step stools & seats to save me precious minutes on my feet. But lately I've broken a good plastic folding stool... my fault & was pushing back on it to reach something & it couldn't take the diagonal pressure. And I'm no light weight, either.
I've noticed a reasonably nice aluminum step stool at Harbor Freight... http://www.harborfreight.com/step-stool-working-platform-66911.html but the latest ads were still higher than I wanted to pay. ($29.99 off a "list price" of $34.99... no one should pay list at HF) I Googled "Harbor Freight step stool" and came up with http://www.retailmenot.com/coupons/stepstool which showed a coupon code 85492649. Since I don't have a printer, I copied all the info onto a 3x5 card & drove to my nearest HF Store. I was prepared to leave the item but I got it for the price. $25.99.
Not cheap but it paid for my gas.
I had a go round with the manager a year or more ago after leaving items when I didn't have a printed out coupon... this is what he said to do & I have been doing so ever since. Same at another discount store as well.
