If you are not in a rush... I buy direct from the source, China. Try aliexpress.com. Lots of vendors on the site, some ship free. I usually price shop for best deal on item from several vendors, place order, then wait a week or three (you can expedite shipping for a horrible price). If in a hurry, Amazon (or Digikey, Jameco, etc.) and pay 4-10 times more for same item they buy from China and get it in a few days if it is a Prime item. If not Prime it is usually shipped from a China vendor just like AliExpress. If it is a US manufactured item usually better to use US vendor. FYI many US vendors/manufacturers have items made for them in China.
