Recently I learned some shippers have a billable shipping weight = greater of weight or dimensional weight.
So size does matter and pricing items boxed is definitely the best way, just make sure you take enough detailed pics. No one needs to spend $ developing film anymore.
Also a "handling charge" may apply due to size.
I tried to get a quote online recently on the USPS website and it stated they don't ship from/to those zip codes. That's a new one.
