I'm not exactly sure. Mostly it don't know because it's an odd shape and I am thinking it would be cheaper if I just bought the brown shipping paper and wrapped it like that then if I got like a flat-rate box or something.
The sleeping bag weighs roughly 2.85lbs. I'm guesstimating about $10? If there was a difference in price I would refund the remaining balance. But if it cost more, then that would just be on me! :)
If it would fit in one of the flat-rate shipping boxes for under $10 then i'd be all for it. But because of the shape i'd have to get the largest one they have which would be around $15. I'll be shipping it in brown parcel paper because then it would be done by weight and would be less expensive.
