not sure about the pricing, but I think you can stuff about 6 yards in a FRE. Try and get the padded FRE's, order online from USPS.com. There is no problem with stuffing those full; there are a few PO's left that have a problem with stuffing the cardboard ones. They have to close "normally" but you can reinforce them with tape. Recommended as their sticky closures are prone to fail.
