I fit the costume into a large priority mail box and the post office said it would cost $16.83 to send to the zip code 19960.
This sounds so expensive, I wish I could send it media mail. They also said it would be an additional $1.95 and $1.20 for both insurance and certified mail respectively.
Again, this sounds so expensive so I am going to update my auction and have the item listed for pickup as well for anyone who might want to bypass shipping.
I just did some research on the UPS website and found that if I repackage the costume and send it UPS I can get the price down to $14.15. This still sounds expensive to me. Let me do some more research to find the best price. Let me know if you have ideas.
