All you online sellers out there, did you update your shipping rates? I spent a whole lot of yesterday revising the rates for my Etsy shop. To get it right, I looked up the definition of letters, flats, parcels and zones because it got all so confusing. I referenced several sites and found the rate information on the United States Postal Service Price List (Notice 123), Effective January 27, 2013, but I like this chart the best. Pictures are very helpful!
