Depending on the size and weight, you might want to consider using a common carrier. I have used Estes several times with good results.
All the best.
Seller Question - I need UPS to come get these large speaker boxes - how to manage that?
Just like the subject says: I cannot fit these large speaker boxes in my vehicle. UPS and other shippers will come get packages often for a small fee - often for free. How do I - as a seller - make sure that gets into this business transaction if I sell these on Audiogon? I want the buyer to pay for shipping. Is this possible on this site?
