how much does the stuff you are getting charged $20 for weigh? that seems really high on a $50 order. i typically pay $8-15 on pretty much anything up to $120 unless i get something heavy or bulky. do a lot of my ordering with kensfish, jehmco, fosters and smith. i buy everything in bulk, but a lot depends on if you can keep it fresh. with me i go through things pretty quick having 100 tanks running.
