Does anyone know if US postal charges are going up anytime soon?

I live in England and often send letters to the US with stamped self-addressed envelopes for replies. Sometimes it takes awhile to get replies - does anyone know if any price increases are planned?Does anyone know if US postal charges are going up anytime soon?
Postal prices are always going up, Dunrobin on this side of the pond. We had a recent one and seem to get them whether we need it or not once or twice a year. Currently 3 of the 39cent (US) stamps seems to get my letters to Ramsgate (Kent) within a reasonable length of time. Does your friend have an eMail addy? Our postal authorities rightly see the internet as a real business loser unless we are sending packages to the UK. Cost me $50 to airmail a box of gifts to my M8's in Jolly Olde E, other wise it would have taken up to two months for delivery.Does anyone know if US postal charges are going up anytime soon?
May 1, this year.

1st class postage stamps will increase to 41 cents.Does anyone know if US postal charges are going up anytime soon?
I have recently heard they are talking about raising the price of a single stamp from 39 cents to 41 cents so I guess that could be a sign... I hope that helps.
Yes next month they will be 41 cents. Today is the first day they are selling "the forever stamp".
