All of my items come from a clean, non-smoking, pet-free home.  I will wrap this up and ship via USPS Ground Advantage, which will be the cheapest. 

****I do not overcharge for shipping!  I charge you exactly what eBay charges me, and I pass on my shipping discount to the buyer.  This weighs 12.9 ounces before being packaged for shipment.  You will be charged for a package that weighs 1 pound, from my zip code in Florida (33541) to yours.****
