Well if an increase on the first of the year was not enough for you, here is another one.

I came across this to today while I was looking for the prices for Express shipping.

The post office is raising their prices AGAIN on April 17th. If you didn't have fun putting in all those by-weight shipping charges the first time, you get to try it again.

If it makes you feel any better, Royal Mail in the UK are also raising their prices in April.

The shipping on some of my international items, now actually costs more than the item itself.
