We do a lot of USPS shipping, so any price increase is always a worry. What I usually do is wait to the changes go into affect, and then adjust my charges after - hmm, losing too much money on shipping, need to increase shipping charge by a little to make it break even again :-)

Per this blog post from stamps.com, the main impact seems to be on Foreign Shipping which translates as about 10%, priority mail is 3.1%, and I am not seeing Media Mail I try very hard to keep our charges for shipping as close to the actual cost as possible.

International Mail
The overall increase for Priority Mail International will be 8.7%.

Express Mail International will increase by 11.6%.

Global Express Guaranteed prices will rise by 6.0%.
