make the contact info request, ebay send hims your info and you gets his.. Usually when a seller sees you made this request an email will follow almost immediately. some sellers worst fear is that a pissed off buyer will call..
Parcel post shipping estimates are not correct.. Parcel post is always the last items processed by a post office, if they get busy, they sit and wait until the next day.. They go to the back of the line. Items sent parcel post can sit for a week before processed.. I have had items I sent make it coast to coast in 3 days w/ 1st class mail and an item I bought from a seller who used parcel post, just 100 miles away take 10 days.. I like you thought it was lost and then the postal clerk explained how parcel post is processed.. After that experience I always ask for 1st class or priority mail..
