What should be the terms between buyer and seller

Good advise given so far but it's not a 100% gauranteed that all will work out! There are only two things that matter with this deal, the seller getting his/her money and you getting the speakers, simple! A few things that could go wrong, shipper destroys the speakers, shipper refuses to pay any claims, seller says I packed them good but don't know how the shipper could damage them, you send the money and never hear anything again from the seller. Don't get me wrong as I'm sure this could be a perfect deal and no problems happening but one must be prepaired for the unknown! Good Luck

Totally echo what Jea48 states.200 lbs. should really be left to Bax Global.Your really stretching your luck with that kind of weight regardless of how the monetary end goes down.Everyone has their comfort level and operates differently,so I wont bore you with mine.If their was 1 sure-fire option we would all do it that way.There isnt....so do your homework and best of luck,Bob

Thank you all for your helpful responses. It gives me a good overview of the lay of the land.
