NOTE!!!!
If you want the flat $4.80 Priority Mail rate, you MUST USE a
FLAT RATE Priority Mail envelope!!!! So don't put a $4.80 stamp on a regular
manila envelope.. If the package is over 1 pound, it won't be enough. If it is
under 1 pound, all will be well.
Also, the online postage will probably print with the date you create it. Which would
make it useless for a later mailing date. Best bet is to buy a Priority Mail stamp and send
that.
Maybe we should give a general guide line for the size of the samples being sent?
