Dark, it would appear that Airgas got you a win this month. I went in to get a fill today. Brought my $1.30 invoice as always. There was a different guy at the desk (Rich, which Matt actually talked to be before). He went and filled the dewar right up. Then comes over, takes my card and brings me an invoice without even looking at the one I brought it. Well, needless to say, I'm sure not paying $2.65 per liter. I asked him why the price changed when I have 4 invoices with $1.30 (from that exact store). He said that it's impossible to override the price unless I have an account. So I asked when that policy went into effect... Over a year ago. To which I asked why I was able to get $1.30 on all my other fills, to which he had no real answer. I asked for my container back, and promptly left.
Some guys are just ***** I get mine filled for $32 and change on a 50L before it was 35L then guy told me hell hook me up if I get a larger dewar hell charge me the same so I got a 50L in a few weeks off eBay
