FYI:

First-Class Mail pricing, effective Jan. 27, 2013

Letters (1oz.) — 1-cent increase to 46 cents
Letters additional ounces — unchanged at 20 cents
Letters to all international destinations (1oz.) — unchanged at $1.10
Postcards — 1-cent increase to 33 cents

The post office just charged me $9+ to mail 2oz to the UK, so that apparently went up as well.

A package within the US went up 22c, from 1.85 to 2.07.

Not sure how that will affect everyone printing the Paypal postage with DC, but that's what'll happen at the counter and the automatic machines.

I just made a label using Paypal Shipping for a 3oz large package/envelope and it went up from the usual 1.64 to 1.69. Not a huge bump but noted
