Love the fact that you show your shipping rates prior to placing orders. Most of the time (95%) I choose USPS Priority, the least expensive

Fast, efficient, knowledgable, good all round people and I will be doing more business with them. I have an older plane and it is needing some refinements. Thanks for your service!
