Yeah all these places seem to have different prices so its good to go and look around for a deal. I pay $30 for a 20L dewar at Airgas right down the road and I never even asked anywhere else sine this seemed to be a pretty low price. The cheapest he ever charge me was $16 to fill up and this was a killer deal but mostly he stays around the $30 mark. I really hate the different prices and will look around a little in the future (once I get of my lazy ass).
I'll be staging a OC party early next year so we'll see how the big LN2 tank delivery will go over with Airgas.
