Honestly, unless someone has a commercially unavailable strain, it would just be easier to make a one-time buy at the LHBS and be done with it.
OP: I'm a little confused here, are you trying to trade with people? If so, why are you not listing your strains or asking for strains that you wish to acquire?
It might be a great idea if you trade several strains at once; getting 5 strains for the cost of postage sounds a lot more attractive and a great way to build up a bank.
