After conversations with various post office officals, I'm told that the 1 lb rule is still in effect. Packages over that weight, pre-stamped or not, have to go through the PO line.
I will therefore not be offerning records on the net or other ways except here, by appointment, as in the past.
For those wishing to make one, the number is 301-694-5134. My email address is smilians@xxxxxxxxx
Should the PO change this policy, mine will probably change as well.
