Ive been calling around to get my Co2 tank refilled. One guy that I spoke to told me that no one does refills anymore because they would have to ship out the tank for a couple days to do it and that everyone does swaps instead. Another company told me that their price for swap was around 22$ plus tax. Now Ive seen on this forum and others that people are getting refills for around 12$. Are people still able to refill tanks and at what cost, or is the swap only rumor true?
