These heavier grouped items can fit in Flat Rate boxes. I will only charge exact - looks like a medium box. Either $11 or $15. Depends on how many auctions you win. I would 'puzzle' pack the box to the best for you. Thanks for your interest.
Flat Rate is always checked by my PO - if you check the guidelines it not approved. I mail 3-4 days a week and they always review my packages. Who ever the winner is - I will pay anything over the $5.00
