it depends what your buget is
e.g. you could make a website with free webs or piczo(for free) and get a .tk domain from www.dot.tk (for free)
what i would sugest is selling it on your on your own website and any other websites that will sell it for you
p.s my website is going to have an fpsc zone (this website will be bort and made on friday i already have tuns of html for it)i am going to post a thread about it dont quote me on this but this is what i was thinking :
if you hav free games or model packs i will put them on my website for free
if you have model packs or games which you whant to sell then i will sell them on my website for either the cost of 1 or i get 10% of the each sale
so if you think my website will sell over 10 then it wold be cheeper to pay me the price of one
e.g. game or model pack costs £10 you can either give me the £10 or you can give me 10% (£1.00) every time someone buys the game from my website
as i sed i will post a thread with more info when the website is ready for that section should be monday
