I do remember a certain manufacturer, a few years before pandemic, raised their minimum parts price to $1.00....so that the washers I used to pay 0.10/each suddenly became $1.00/each! So much for the "save the research time and get it direct from the manufacture"
I will point out that you can get free shipping with only 5 of them at Full Compass
I also remember when Crydom was bought out, my cost for a 40A SSR went from $22/each no minimum to $75/each under 100 pieces overnight. Turns out that it is now cheaper to purchase a SSR from the manufacturer than a supplier.
