Anyone know if there is a way that eBay won't notice to tell the seller you want to pay cash in person and that you'd like a discount?

(seller says local pickup available, and since they have "free" shipping I'm assuming that's rolled into the buy it now price, so I'd sort of like the money they would have spent on shipping back to me and they also make a bit more by not paying the fees)

(it's a pair of sneakers, not a high ticket item)
