Earlier today I said I was watching 3 things that were already low priced. One was the mortar that I posted. Right after I posted about the mortar the other 2 things dropped by another 90%!
Lowe's has 2 LED headlamps on clearance, listed below. There was a Lowe's store near me that had both in stock. The first headlamp was about $7 with 10 in stock, and on lowes website. The 2nd headlamp was about $7, 14 in stock, but not on Lowe's website.
So a week ago I visited the Lowe's store to see if they were in stock

I only found a display of the first headlamp, and there was only 4. It was very likely the rest were in the overhead bins they store flashlights in. I decided to wait since the price would just keep going lower since no one could buy them.
Today the first headlamp dropped to $1, and the 2nd headlamp to 50 cents

I placed an order for the one headlamp on lowe's website. When I got to the store I went to the shelf, and they were literally taking them out of the overhead bins. So I asked the friendly Lowe's employee if he could look for the 50 cent LED headlamp that they were supposed to have 14 in stock. He looks through the bins, and found 8 of them

I left without about a dozen total.
I should note that the 50 cent LED headlamp is listed as 215 lumens and not 210. I assume there are 2 products with the same UPC. The model, etc all matched except for the lumens, but it rang up 50 cents
Also note: I have seen these on display in the lumber and HVAC sections. So even if there's none of the shelf they could be in the overhead bins, or in a display somewhere in an aisle.
