I would start wrapping better as well. Tissue paper is cheap. I'm going to start using that. Some customers will ask for it.
It gets kind of bulky with tissue and bubble wrap though, Doesn't it get crushed with a Regional Rate A, especially with both top and bottom?
I've used a medium flat rate or large priority box before, but I don't sell many suits (yet)....
I don't know why you need bubble wrap for a suit. I've never seen tailored clothing get shipped with bubble wrap from a regular retail outlet before.
