Where do you go to get Double Boxing Services?


Was looking to find out where/how people handle boxing and double boxing. A couple of a components I plan to list for sale were bought back when I didn't think I needed the original boxes. Now, I want to sell them, but was wondering about where people go to get them boxed. I live in West Los Angeles, but I'm sure anyone could have a good idea or two on how to handle things properly for our buyers!

Has anyone used this service to send large speakers over long distances via UPS?
Another vote for Mailboxes etc.--they have been very good at packing some of the larger items I've shipped.
Judit, I've never had to ship large speakers. I would probably try to replicate the original shipping carton, but I realize that can be quite expensive. Although my 73 lb. ATI 1505 came in a double thick cardboard box, I would think anything over a 100-150 lbs. might require a wood crate. Yikes!
