The TOROMONT bottles come postage paid. You slap the bottle in the shipping bottle and drop it in the mail.
oilyriser: Given the recent Blackstone thread (that magically disappeared) about testing inaccuracies, I am willing to cut TOROMONT some slack. I can pick the bottles up locally, the shipping is free, and the price makes it a no-brainer. I also like the report layout. Also, given the majority of their clientèle (heavy trucks and garages who service them) I imagine they are pretty good about keeping their equipment in calibration.
