USPS shipping rates going up

Shipping costs are going up on January 27. From what I can tell, the most significant increases will be for international shipments, with the base rate for Express Mail (EMS) to go up a full $10 -- to $35 for Canada, and $45 for everywhere else. Priority Mail service outside of the USA will be going up significantly, too. The new rates for a Flat Rate envelope are $20 for Canada and $24 for everywhere else -- and much more for anything that won't fit in a Flat Rate envelope or small Flat Rate box.
