-> I didn't get any calls and they don't seem to have any hard limit, either. (Still, don't abuse it.) 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.)

-> If you are not a company it is possible to get your request denied, this is because TIs help-pages about ordering-information are wrong/​lacking.

-They allow you to sample their 8051 MCU's but not other ICs. 4 different parts per order, with 8 parts total, and 3 orders in a 30 day period. 
-UPDATE: ​ They are now allowing samples on their new line of ARM processors. ​ I just ordered two SIM3U167-B-GQ (ARM Cortex-M3 USB 256KB TQFP80) which are nice ARM processors with two integrated ADCs and it didn't seem to be a problem.
