Last week I ordered a bunch of parts from a distributor but noticed the next day that I had forgotten some. Rather than cranking up our in-house purchasing red-tape department for another order, I just ordered the missing parts as free samples from TI and Freescale.
The TI samples actually arrived ahead of the paid-for parcel.
I wonder what the actual cost for the sample shipping is. The parts are nominally worth $20 and arrived in Germany FedEx priority from Texas. At no point during the ordering process did I leave the impression that I'm expecting to generate sufficient business for TI to at least break even on the sample shipment.
Anyway, since they only have a sample order for but no "Thanks" form, I decided to use this group for that.
