I don't even keep salt water tanks and I find paying the $20 is well worth it.

Tons of great advice, excellent deals and honest people.
As for getting donations from companies I participate in the local EIAA club and donations have gone way down as more and more companies merge under larger corporations. Our club probably received 1/3 of what it used to this year in donations some of this is driven by ecomonics but alot of it is the merger of alot of companies under 3 main umbrella companies.
