It's been 8 years since I left but I used to do a good bit of purchasing and back then
had the best prices for Alpha wire, JST and Molex connectors, Omron relays, and various tools. They carry some other items but no semiconductors. Look at their list of brands they carry and contact them if they have items you use. They probably do have some kind of minimum order but I don't recall so it must not have been a bother.
Hi David, AFAIK most spam blockers allow you to white-list a website. Since Mouser is a valid site for vending products but probably does engage in all the other craziness like 3rd-party scripts, affiliates, and tracking, I see no reason not to white-list them, and do a clear-cache afterwards. But if your position is philosophical, you feel you shouldn't have to do that extra work, then OK, don't shop at Mouser. But you are probably on the losing side of the battle, as more sites monetize their main business revenue with marketing our personal data. Whoever said "technology will save us" had no idea..
