For shipping, they allow you to pick from FedEx Ground, 2-Day, and Next Day, none of which cost anything to you. Also, I might just be slow at catching on, but a lot of manufacturers (National, TI, ST, etc.) look like they ship a lot of their samples from Thief River Falls, Minnesota. The specific address they ship from matches with Digi-Key's address, so they're probably forwarding the sample requests to Digi-Key for fulfillment. (I think Fairchild forwards to Mouser, if the Mouser box I got is any indication.) Just something to add. | + | > I didn't get any calls and they don't seem to have any hard limit for request frequency, either. (Still, don't abuse it.)
