This has been my play since last February. In some ways it sucks, because Amazon really cornered the market on niche solutions to niche problems. However, when there is something I absolutely need I try to look for a local solution and if I can’t find that, I use eBay. By no means a perfect solution (ie. a lot of the eBay vendors still use Amazon to fulfill their shipments) but my mindset shifted from “oh yeah go on Amazon and press Buy Now immediately” to really working through a solution, and whether or not I need to purchase an item to enact that solution.
