after looking at all these replies , the common denominator is that bad guys will try to take advantage of situations where money [ in any form ] is involved -- if you really want to cover all bases and be safe in all transactions in todays society , you must realize that there are bad guys that have varying degrees of skill at their " art form " , as for example , the bad guy seller who ships a brick or tire iron instead of an airgun . so , to be safe as a buyer or seller , it has become necessary to document all transactions -- i.e. when boxing up a sold rifle or unboxing a bought rifle , the best way to document would be to film / take pictures as you box or unbox - yeah , I know it's a pain in the rectum to do so , but who would think it would ever come to taking your life in your hands by going to a movie , attending school , running a marathon , or attending a music concert ??? it is the way of life NOW IN THE PRESENT , and appropriate counter measures are required to combat bad guys , whether it be terrorists or scammers -- for me , paypal is the best method - backed up with film documentation - if anyone has any better ideas that will cover all the bases , please post it - BTW - people have been bringing back items to brick and mortar stores under false pretense to receive illegitimate refunds for MANY , MANY YEARS - this is not a new trick - just a new spin on an age old scam - I will continue to use paypal / I realize that they do not want to get involved in firearm transaction and I can see their point - imagine a paypal transaction where some 17 year old kid buys an AK-47 through paypal and then decides to shoot up his high school -- does paypal have any liability in that mess by making it possible for the kid to obtain the weapon ??? I don't know - sounds like major lawyers and lawsuits to me --- PAYPAL is smart in avoiding those potential disasters - it's their business , and they want to avoid potential liability . if you are going to blame them for not dealing with firearms , well , it's all on you - by the same measure , some restaurants don't serve liquor , or don't stay open past 8:00 pm - their business / their choice
