These cushions are on Craigslist, and not ebay. Craigslist is quite a different animal than Ebay. With Ebay, one generally purchases through a system called "paypal" which provides some protection if the seller turns out to be a scoundrel and doesn't deliver the goods you bargained for. With Craigslist, it is just between you and the seller, with no "scoundrel protection."
With Craigslist, an often stated warning is to never purchase anything without doing it face to face with the seller. The converse is true also; most sellers will not ship their goods without getting payment up front (which you as buyer do not want to do). In fact, many sellers will state in their ads that they will NOT ship the goods.
Please note that our friend and site member NYMack is not the seller of these cushions. He has just pasted the ad on to the V20 site in case anyone is interested.
I note you are in Memphis and these cushions are in the Fort Myers, FL area. I would caution you to not make the purchase long distance. However, you may be able to sweet talk a fellow member in the area into making the purchase and shipping them to you. I would trust anyone on this good site, but not the long distance seller from Florida.
They do look like nice cushions though, and from the picture they look like they would fit in a V20 cuddy nicely.
