12 years ago I went to Home Depot to buy a hospital grade 20 amp duplex and a weatherproof outside single box as I was wiring a 30 amp protected circuit about 25 feet using #10 Romex from the panel to the outside wall.
It was to be used to power a motor home using a 100 foot #10 power cord housing a 30 amp protected panel.
When I went to check out, the clerk started to ring up 59 cents for the duplex since it was white in color like the typical contractor 15 amp grade.
When I informed her that she was costing the store a bunch of pennies she called a manager who said that if it was 20 amp it should be grey and would cost $5.00; I said, “No, it is actually $15.00” and it was clearly marked as to its purpose and price on the shelf where I picked it up.
Still not satisfied, he wouldn’t relent until I took him back to the shelf and pointed out the SKU along with the model and designation specs.
This was not just my sense of honesty at work, I had already been here in Nashville long enough to realize that there wasn’t a clerk in a single store of my experience who was on the right side of the counter.
After all this time my opinion hasn’t changed.
I've been in more-or-less the same situation a few times. Generally, when I point out the mistake, the clerks say "Oh that's right" and charge me the correct price. Others thank me for my honesty, and give me the lower price...(depends on their position, and whether or not it's a big box, or Mom and Pop place).
I've had a couple give me an argument..."This is really a 99c item, not 24.99". To them, I say "OK, it's a 99c item." So be it on their head.
To all on this thread who say "So what's the big deal?" I ask one question of them... "If they were *overcharged*, would they point it out and expect their money back?"
