My brother has used this technique. You get the seller to bring the glasses to a pawn shop. You are on the phone with the pawn shop. They verify the glasses are real etc. you pay the pawn shop fee included and shipping. The pawn shop gives the person the cash takes the glasses and ships them to you. The fee for shipping and inspection is usually >20 dollars. The same principle go with buying firearms. A pawn shop has a FFL license and can ship firearms. So that offer a service. Well most of tem.
