I think I’m set for life when I need SMT transistors – I bought hundreds of them from Newark Element14. They are having a discount sale; some of these transistors are discounted to less than 2 cents apiece whether you buy 1 or a thousand. Some are as low as a penny – $0.011. The discounted ones have a red circled star next to the price. So I bought a hundred or so of the most used transistors. They have many other parts discounted, too, and shipping can be free, depending on the carrier.
Note: I checked the datasheets. Some of them were mislabeled, in other words the datasheet was for a SOT-23 package but the transistor is in a different package, even smaller than SOT-23. So check to make sure you are getting the ones you can use.
What I bought. I edited out some private info.
