Are you saying that the local merchant tests it and that's why they sell it at 250x the price?

I said 10$, but it depends on the length. So 60cm is maybe 10$, 70cm is 12$, 80cm is 13.50. So you would say that testing the 70cm variant of the zipper is worth 2$ more than testing the paint on the 60cm variant?

My point is that at this price, if I don't get the zipper on Temu, I don't get it at all. I won't pay 10$ for a zipper of this quality.

I've noticed a similar 'this profit margin seems almost vulgar' on the same store shelf.

As you showed with slightly longer zippers.. I notice with car fob remote batteries. An 8 pack is $12 at the store. The same brand, a single will be $5. A 2pack is $7. And the 8pack $12. Do you really need to make $4 on selling me a single? I know shelf space is valuable, but the same store sells things for $1 too on another shelf so apparently <$1 profit shelf space is possible.

Given how small the batteries are, they probably have similar costs for shipping and handling. So there's a cost to get _anything_ to the local store, plus the cost of the actual goods.
