I offer paypal FF or add the 3% for G&S. Either way I cover the shipping. I couldnt care less if you use FF or GS. If you want to pay the 3%, I just have an amount Id like to net in the deal. Whether someone uses FF or GS +3%, I net the same amount. Should be the standard. But if you are new, and dont have some feedback built up, you should just do yourself and the buyer and favor and not even mention FF.
Ive also sold probably 100 items and bought probably the same amount without any type of issue. You can look at my history and feedback. Im not making "good luck" posts to reach the 10 message limit or starting threads right out the gate complaining about having to wait 7 days and 10 posts in order to get 10 posts.
A couple rules to live by: If its too good to be true, it is. I usually only buy from people with good feedback and/or have been around for a while. I understand people have to get feedback, but for me, I just try to avoid being the first for items over a few hundred bucks. Especially if the person just joined 7 days ago and use the english language in an ultra creative way.
That being said, I think we as a community need to get better about leaving feedback on transactions. Like I said, Ive bought and sold a hundred+ things here without issue, but I only have 12 feedbacks. We probably need to take the feedback more seriously for the greater good.
