BRAND NEW FAST SHIPPING USPS, UPS, FedEx & DHL Approved On the subject of shipping cost or speed: I always do my best to weigh and measure each and every item to be as accurate as possible so that I can choose the cheapest shipping each and every time. Please do not write me to ask for me to find cheaper shipping- I am limited to what is offered by eBay. I do not guess at any items weight or measurement ever. I actually put the item in correct size box and add packing fluff to get correct weight and closest measurements for each and every item. I do this to be as fair as possible and to keep costs down. If you would like expedited shipping please contact me before you purchase so I can open more shipping options for you. Thank you for understanding.
