Padded mailers returned for postage due
It seems like 3 stamps just isn't cutting it any longer for a padded mailer (SASBE). Up until recently I've had no issues when using 3 1st class stamps and sometimes even 2. I'd infrequently have an envie returned for postage due but now I'm getting more back then are going thru, even if they're under 1/4" thick. I took several of the returned envies to the PO and it appears that it's now $1.95 to mail a SASBE. Has anyone else been having issues with using 3 stamps?
