Seems to me it's becoming more available in recent years. I've used it on and off for 50 years, or so, and there was a time it became difficult to find. But I used to buy it in Grants, New Mexico, during the early 2000s, and for the past few years I've bought it in Junction, Texas, small town, and at the HEB in Kerrville, Texas. Price at the moment runs $1.60 per pound. Comes in 5# packages, but they allow you to break off however much you want and weigh it at the register.<br /><br />For me it's always worked as well as ice for any purpose, better than ice for frozen foods. A pound lasts as long as a bag of ice and unless you need the water from the melted ice, the dry ice eliminates a bit of water waste.
