Upload & Sell: Off
I used paypal gift a few times until I found out that it's duping their system and you aren't protected from it. Think of it this way:
How many times have you been to a restaurant that doesn't take credit cards? It's a bitch isn't it? They don't want to deal with the 2+% transaction fees. As the buyer, the convenience of using a credit card is gone and when you think about it, it's just 2%. Even at a really expensive restaurant, it's not that much.
When it comes down to it, I only sell using regular paypal but when I am owing a friend some money (usually not much), I'll paypal gift it.
Again, at the end of the day it's like 2% and you're protected so regular paypal is good enough for me. If I was buying from people on FM, I would prefer the price be a little bit higher with regular paypal than cheaper with paypal gift. If it's a lens over 1000 dollars, I would definitely want regular paypal.
