International mail got hit hard with price raising. First class to to Canada went up over 60%. Mexico is no longer on the cheaper tier that Canada is. Lot's of grumbling all over the internet. Priority international flat rat envelopes went from $16.95 to $24, and that includes the discount for electronic printing.
Thinking myself and many others won't be shipping as often internationally, the cost is just too prohibitive for them
USPS, penny wise and pound foolish!
