back to gwb.......I should probably ask sometime that we "sticky" a "how to do a gun deal" here somewhere...........since it is for sure a common question.
The key to a good deal here is good comms BEFOREHAND. Both parties to a transaction should agree completely on all of the terms of the deal, and generally there will be no problems. (Yes, you can get into what constitutes "NRA Very Good" or whatever, but usually that kind of thing is either outright fraud by a seller (RARE) or a genuine lack of knowledge about the piece being sold.)
EMT is the best and slickest way for a buyer to pay a seller, and once a seller recives the EMT, funds are instantly in their bank account. Some folks here still use (FRAUD ALERT) (owned by anti-gun eBay), but you can probably guess that most of us do NOT patronize (FRAUD ALERT). In my own case I also accept personal cheques, money orders, direct bank deposits, Canadian Tire money and pretty stones. The key (again) is both parties agree to how payment will happen.
I guess it is about fifty-fifty whether folks transfer the firearm before or after receiving payment. The safest way of course is for the seller to receive payment before starting the transfer. For myself, I generally initiate the transfer as soon as I have the buyer's information, but if I get a funny feeling about the deal, or if the buyer has zero trading history, I might wait until I have the money. I do suggest waiting for the transfer to be completed before shipping, but I have certainly shipped as soon as I have a reference number. Again, it would be a gut call, do I have a good feeling about this deal? Is this the buyer's first deal here? etc. If you ship before the transfer is approved, obviously you need to agree with the buyer that the firearm is ON LOAN, based on the valid PAL and reference number, until the transfer is approved.
Hope this helps. If you have more questions, don't be shy.
