USPS flat rate is the best thing going in my eyes...
I've shipped many chains cross country for $5.20. usually in two days too... and their trucks roll on weekends to...
I've sent stuff on Friday and even Saturday that got there Monday..
Just.. don't ever use Parcel Post...
Lotsa horror stories about Parcel Post...
A lot of guys have bad luck with USPS... but I've been shipping stuff a lot in the past 10 years and never once have they lost anything..

Build it the way you want it ..... then learn how to ride it like you own it..
