I did find 3 more fire extinguisher places, but 2 don't fill/exchange and the 3rd want $38 for an exchange - which is ridiculous. There is also an indoor paintball place in LI City but they don't fill/exchange co2. For the time being, it looks like I'll be heading to Mckinney's around 6:30am before work, assuming my tank comes Monday. They are by far the cheapest at $18, but it sucks that no one else is open on the weekends and close by. Bitter and Esters are open on weekends, but will exchange the tank for $28. Don't think I will be going there given that price/commute time unless the tank arrives earlier than expected and I can't wait for a weekday to fill it (which is what will likely happen)
Time to find a new place to live
