Ok everyone - it looks like the tanks will be about $5-7 each regardless of size, although I'm still not 100% certain. I believe a flat rate envelope from USPS is $5.95. For those wanting more than one tank I am thinking I can mail several tanks in one envelope to aid in lowering shipping costs. Does this pricing sound reasonable enough that everyone is still interested?
