accept address buy cheaty ebay flag form forward gram guest guy located meaning money number online page payment paypal phone protected purchase sandbagers scammer seller sellers site skeptical sound system thank-you trustable union verify western

I wonder to know if there any way to verify how trustable are some sellers. I tried to buy from some of them and at the moment to ask for payment form, they just accept western union or money gram, which is ok, but how trustable are they?, why they dont tell you where are located?, a real phone number, not a forward number, real address?, etc. they sound very "cheaty" or "sandbagers". One of them I went to western union and they told me that the guy has a flag in the system, meaning, he is a scammer..... today I was looking for they page here and guest what?, no longer online.... make me more skeptical. How we can very the seller here?, are our purchase protected in any way like other site as ebay or paypal? Thank you
