So I swung by AutoZone to pickup some Mobil 1 0W-40 and thought to myself, I shouldnt use logs and just get some cheap chocks. Well did I ever. I found a set over on an unmarked clearance table and asked her to check the price for me (which was no where to be found). It rang up @ $0.01 with a 70% off discount of $0.01 making it free! She couldn't believe her eyes and printed a receipt and showed it to the three other associates at the desk. They all confirmed that it was the right sku, model, product and price and said it was my lucky day and that was that. Then I was like, well I really need another set for both rear wheels. So I searched the store high and low, and finally found an open box at the top shelf next to some floorjacks and jack stands (I know great, what if those were to fall on someone?..) and tried my luck again. Sure enough they rang up at $0.01 regular price, with a 70% discount of $0.01 and walked away with two sets of free wheel chocks. So yeah they're $15 a set on Amazon + S&H but free is even better
I joked with the clerk and asked if I had to pay the tax on $0.01, they let me go
If you want to skip the story, here's the low down.
