the town i live in has a couple of those old hardware stores. the nearest supply house to me is 30 miles, so every now and then i have to drop in at one of the local places and pick up something small to save a trip. at one, the electrical shelf hasn't been restocked in probably 15 years. they have a QO GFCI 20A breaker for $69.99. A 15A recep is $1.20. We also have one of those "do it best" hardware stores that just came to town. You can buy 100' of 12-2 romex in a box for only $59.99. I had to get a gfci recep a few weeks ago it was $20. Today, I needed a couple of 1/2" emt outside pull elbows. They were $6.99 + tax. Inside pull elbows were $7.29. When they first opened a few months ago, i went up there to get some device boxes for a small kitchen remodel. They were $2.99 (metal) a piece. I didn't realize that until the cashier rang them up. After picking my jaw up off the floor, i put them back on the shelf.
--- forgot to add: i needed a dimmer once for a patio i was building. i went to the local place that had to $70 gfi; they didn't have any. the guy offered to order one, and i was in no hurry, so i told him go ahead. after spending 10 minutes looking at a 5 year old cooper catalog, we found the product number for an old rotary dimmer. he wrote down the order, and said he'd call me in a couple of weeks. well, a couple of weeks went by and i forgot about the one i ordered, and got one at the supply house. i got a call 6 months later from the hardware store; my dimmer had finally arrived!
