I recently started work for a major dry ice company primarily supplying the MidWest, Central South, and East coast of the US, as well as parts of Canada (however, shipping can be done outside this range). Knowing some businesses are looking to "complete the circle" and purchase their supplies with BTC, I thought this could be of some interest, particularly for our meat industry (Omaha Steaks is currently the largest purchaser) and'd love to be able to put together a compelling set of documents for corporate with a list of real companies which'd be interested in making purchases in BTC. Our dry ice pellets also make an excellent, environmentally-friendly cleaner for heavy-duty objects using dry ice blasting, particularly in knocking oxidation and any other unpleasantness off pipes and metal connections quickly and with far superior results to air or water blasting, and being much cleaner than many conventional harder blasting methods (and unlike most traditional hard blasting methods, dry ice blasting can be done inside the factory).
Dry ice shipped is considered food grade and is generally in a purity range of 99.95-99.98%. All of our containers are thoroughly cleaned and sanitized each time they're returned (and they're sometimes returned with the most bizarre stuff inside, from doritos to whiskey to gold bracelets) with strict quality control measures in place on the line.
Dry ice typically costs <$1/lb, with less-processed types generally being cheapest (

operating range, CCPI can use its own trucks to ship directly to you and minimize shipping costs.
Some side-notes: I'd suggest trying to get poly-sealed or naked blocks if you can -- Kraft bagging is a nightmare and it's difficult to determine if the ice broke during wrapping or packing, while they'll all stick together once packaged (in which case, you'd probably be better off with a naked block). The airport cuts are cheap (they're reformed from scraps), but tend to be more ugly/deformed/non-whole and have unappealing bagging. High-density ice is generally a good option, though they probably won't tell you about it unless you ask -- they tend to be fully intact more often (and prettier in general) and you can use less to cool more for longer, saving on shipping.
