We see a lot of merchandise change hands between individuals on forums like LRH. Most of the time they work out well. Occasionally someone gets cheated; sometimes it costs BIG bucks. IMO, that means we should all consider how transfers are conducted when buyingfrom or selling to strangers we contact in these forums. Whether there's an FFL involved in the process or not, how the funds are transfered and how the product is delivered can make a huge difference. I recently read a post on another forum where the seller sent an expensive scope and accepted a personal check. The buyer has gone incognito and the check isn't worth the paper it's written on. Few of us can afford to give away or valued equipment or our hard earned cash. PayPal is a popular method for receiving payment. I use it quite a lot. But, as I understand the policies outlined on this page (https://www.paypal.com/us/webapps/mpp/security/buyer-protection) PayPal's protections don't cover all types of transactions. A favored method of transferring funds using PayPal is for the purchaser to classify the seller as "Friend". The PayPal web site says "Purchase Protection also does not cover items that you purchase in person, or money you send to friends and family." Likewise, as I understand the policies outlined on this page (https://about.usps.com/postal-bulletin/2013/pb22367/html/updt_002.htm) USPS accepts any of three types of payments from the recipient - cash, or a personal check or money order made payable to the mailer. Personal checks don't always finish well in the race to the bank. What I find at (http://www.ups.com/content/us/en/shipping/time/service/value_added/cod.html) is that UPS will accept personal checks on behalf of the shipper, but if the shipper requests another form of payment (cashier's check or money order) it will not accept a personal check. There are certain nuances associated with every delivery service. For example, I believe UPS ships COD only to one of their own stores and the recipient has to pick up the package there. My point here is, whatever method you choose for transferring your cherished equipment or your hard earned money, take the time to check the shipping service you intend to use so you know exactly what to expect if something goes wrong. I make it a practice to always go to the shipper's web page and get the most current information on how they handle transfer of funds. I'd recommend everyone protect themselves in similar fashion.
