That would definitely have enriched my comment, but, unfortunately, I couldn't think of anything in particular in the moment, and can't now. seb1204 (https://news.ycombinator.com/item?id=43564922) mentions one common kind of use case for me: I want to buy some small utility item that I'm used to finding in the hardware store, but it's sufficiently specialty that it's not worth it for the hardware store to carry it, and it's sufficiently small that its price would triple or quadruple if I paid the manufacturer's shipping costs.

> I've been Amazon-free for a while and generally I've had very good luck simply going directly to manufacturer's websites, but it seems like you might be searching for a class of products for which that strategy is ineffective?

As I say, I'm stuck in the situation of being vague because I can't think of the last specific time this affected me, but I have definitely dealt with relatively small sellers where the purchase option on their webaite is "here's a link to buy from our Amazon store."
