I honestly have not had a chance to go to post office and have it weighed yet, but I "guestimated" a weight on usps.com for a 2.5# package and it was anywhere from $8-12. I have to look into a bit more cuz someone told me that if you use there "flatrate" box & shipping that it would cost $6 to ship anywhere in the US. I actually checked and if it fits into a small box it would be that price, if it has to go in a med size box it would be around $12
