It's not that bad. if you are sending anyting heavy and in a big box expect the charges to be large.
but if had shocks from texas shipped for about 30 incl taxes, an ims oversized tank from cali shipped for 40
If its not oversized USPS is the best, but they pay the terrifs upfront. UPS charges a brokerage fee of about 20 so I try to only use them for large items like ferrings or plastics...
I guess i'm used to it cause i'm one of them EHH
