How cheap is cheap for you?
$1/gal is sort of standard, but it also goes along with supply and demand.
Post what you want and what you want to buy. There was a guy in NY that was having a completely insane deal on tanks...and he was posting here stuff that was WAAAYYY cheap. I would have jumped on it but no more denero with xmas.
I got tanks to sell but there were a lot out there so I'm waiting a few weeks for it do die down. A 40gal breeder (lizards), 45 mirror rear, and 55gal complete.
CL toward Boston always has em cheap.
