Flat Rate Green: everyday low pricing for shipping

For packages between 2 lbs and less than 20 lbs, Flat Rate Green will likely win. Simply input dimensions and package origin/destination to calculate the Flat Rate Green price. No need to select anything, no volume commitments. If you enter package dimensions in the ShippingEasy app, we automatically give you the lowest pricing on Priority Mail items (in most cases). Bottom line – always enter dimensions to enable this pricing on every shipment.
