Just an update.

Yep. 34$ to get an change for a 5#. Crazy. The 20# is only 3$ more. Will get that next time lol.

They did help out on the exchange fee as my can was out of date and waived that. Also they looked at my record and saw I paid 14.76 last time I was there. OUCH. The guy even remembered me lol

Btw air gas is food grade. So it is clean co2 of anyone was wondering. There was doubt since they do welding.

Will have to find alternatives.....

I think so, cuz I was gonna buy a new tank but when u give it to them it anyone unless it's to fill it's gone. But give them a call an see what they say they might take your tank if u got one an put it into their rotation. I went from the start an got a tank from them for $100 and now I do the whole $25 every few months.

Where have u been? I sent u a text to grab the plants no answer. Anyway I still got some if u need some as the others melted in tha bag waiting for ya LOL.
