Here, I present evidence of . . . something.
On Saturday, I was at the Home Depot buying some hardie board as I continue working on the basement bathroom. They no longer carry the kind of hardie board I'm used to using, but the stuff they had was similar in price and size to what I'd been using, so I got it.
At the checkout, the UPC scanner couldn't read the symbol printed on the board. The cashier looked it up in the system and said "Okay, $36, does that sound right?"
No, it did not sound right. The price on the shelf was $14 and some change. But the cashier insisted the price was right for the merchandise. Maybe the sign was wrong, I thought. So I paid.
But all that day and into Sunday it nagged at me. So I got onto their webiste and found, yeah, I'd been overcharged $12 a sheet. What they'd sold me was their bigger sheets, but I'd come home with the smaller ones. The ones I need.
So back to the depot I went on Monday. That meant finding the receipt -- not a problem, I have them in a folder like the nerd I am -- but it also meant hauling the six sheets of hardie board out of the basement and back into the car so I had some kind of physical "proof" that I had indeed bought them. I wanted to avoid that step, but Michelle said it would probably be a good idea to take them.
I did get my money back -- a total of $126; the tax alone almost paid for a single sheet of the stuff I needed. And they did indeed want to see the stuff I'd bought. I'm glad it worked out. Next time, I'll be a bit more stubborn at the store.
