We pay $25 every 4 months. Our ABS rep fills us. Genex in Strafford, MO is about an hour away if I think we are getting low and have used them a few times (when we are doing a ton of AI over several months), they charge $20 but you have fuel expense there.
Local welding shop $22.
Do not trust ABS, I let the rep talk me into it, he missed me @ 90 days then came late, then he did not fill he said it was empty, I just plain got forgotten, lost $$$$$ is semen and embryos. :bang:
Our current Select Sires price is $50 for 4 months. Going to have to look into other places. Checking to see if any welding supply stores are local enough and offer Nitrogen.
