A 10 X 13 envelope (must be less than 1/4 inch thick) is considered a flat and costs 80 cents for the first ounce and 17 cents for each fractional ounce after that up to 13 ounces.
The cost depends on weight and distance, just like any other mailing container that is not marked flat rate. The retail cost will range from $5.60 to $11.25 (1 or 2 lbs.), a bit less if you print online prepaid postage. You might want to reconsider and send the poster in a plain mailing tube via First Class Mail if the actual weight is 13 oz. or less. Then the maximum retail cost is $4.12 plus the cost of the tube. ~~C~~
