Ok I think I just experienced a reason for the change.
Placed a tape measure inside a small box then in one of those cardboard containers amazon mails their books in. It easily fit in the flat rate envelope, my customer ordered expedited. Yet when I got to the grocery mail center, the lady said the Postman told them not to accept those items, EVEN THOUGH my item more than fit and it more than sealed. IN fact, it had a ton of extra room so it more than sealed.
She said the USPS is recalling a ton of items mailed in flat rate envelopes and boxes and sending them postage due.
So then I said well they don't know how much I spent but I spent $4.75 so if you would deduct that off of the $10.20 cents, that would be great. Yet I remembered Amazon put the amount of postage on the label. So I paid an extra $5.45
So my tape measure weighed exactly a pound before shipping so no way could I keep it at a pound. With the envelope it was an ounce or two more but had to put it in a priority cube size box (Not flat rate) for mailing. And it would cost the exact same as the HUGE priority NON Flat rate box 
SO I figure unless you sell stuff that goes for first class or is very large, customers are going to have a difficult time believing the shipping charges are not padded.
End of rant   | 
thanks again
