Post a screen shot of your order history at your favorite parts supplier. Here's mine for Smallbear....probably about 30% of all the stuff I've actually bought (Mouser gets most of my monies, but my order history there is several pages long).
I'll play along ....
Smallbear and PPP almost certainly get the bulk of my parts money, though Tayda gets ordered from more frequently and a lot of the basic parts (caps, resistors, jacks, and switches) in my house are from them. I like all three of them, really.

Note the embarrassingly large number of times they summed my orders. To the point where they did it automatically on 9/5.
