Very rarely will you find anyone willing to trade Anubias sp., unless you have that one UBER UBER UBER rare plant. Even then, it would be a reluctant trade.
On the other hand, our sponsor, www.aquariumgarden.com
, has Anubias sp. for a relatively low price even after S/H. Robert of www.aquabotanic.com
also offers Anubias sp. for a pretty low price. Coupled with free ground shipping (which is perfectly fine for hardy plants like Anubias sp.) for APC members, it's pretty much a steal.
Local fish stores usually charge more for a variety of reasons, one of which is rent so they're not out to deliberately 'con' you.
Sometimes it helps to realize that this is only a hobby for us; but it's a 'way of life' for them.
