I just got a sample packet of boxes from my mail man today that included a new box for regional rate shipping called "regional rate box C) It's HUGE! It will probably hold 100 bars of soap, although I haven't checked, but the weight limit is 25 pounds. I haven't looked at the price for shipping it yet, but the other two box sizes are really cheap. These new boxes would be great for shipping gift baskets or things that don't weigh a whole lot but have some size to them. I just hope when the post office cuts services like they say they are going to that flat rate and regional rate services don't get cut.
