A plus: they have stock that MusicDirect, Acoustic Sounds and Elusive Disc don't have.
A minus: you have to pay for shipping. MoFi should have a policy like the others that if you buy a certain dollar amount of merchandise, shipping is free. It's unreasonable to pay high costs for MoFi products and then have to pay for shipping on top of it. Add to that the poor customer service and it's a big NO for me.
