Serious question: what did GG give you that you couldn't do yourself with a simple web shop?
I guess it comes down to my personal skills. I wouldn't know where to begin with making my own webshop or paying the money to set one up. If I had to do it again I know there are things like Squarespace these days that would probably be pretty easy to use.
Also, I set up my GG store long before the whole Reto VGS/Coleco Chameleon fiasco. I lost a lot of regular customers because of that. Even though no percentage of my sales was going towards the previous owner of the site (I had an unlimited no fee account), many people refused to use GG on principle. But by that point all my listings were on GG and as I said before I lack the skills needed to easily transfer them somewhere else so I kept them there.
I am actually hoping that with a new owner some of my old customers will come back. Selling items online is just a hobby for me so if it does well that is great, if not I'll find another place. Or just sell through facebook or something.
