> I've seen people shopping for hardware on reddit say that the navigation is clunky and confusing, and IIRC they said the products are price-gouged?

I think these people are used to shopping from Amazon and Home Depot. They can get their bolts and random specialty items and it comes cheap. When you’re talking about a quality, precision piece of hardware, one where you know the manufacture and have reliable dimensions (and probably even a CAD model) it comes at a price. And if you’re working On something that matters, especially if this is your business, you’re willing to pay for that.
