I used McMaster-Carr when I had my business. Time is $$$. McMaster has excellent service, super fast shipping, a huge inventory and have spent the time & $ to give complete information about the products they sell. If those things are not of value to you then eBay might be worth it. Speed, price, quality - used to be pick any two, now down to 0ne. Nothing wrong with being cheap but it comes at a price.I have never ordered anything from McMasters due to the shipping rates
