its a good investment for future stuff
specially to buy/sell stuff here on d2jsp,
sorry to inform that game was costing 13 USD, now back to standart price 40 USD.
they do SEASON DISCOUNT with 67% discount on D2R only two times per year. there are more other discounts but not 67% one, the 67% only one or two times per year, and just finished one now like 10 days ago.
if you earn some FG here on d2jsp, selling items, or providing services, or what ever, you can EXCHANGE your FG versus D2R copy, 100% legal. you need add to your friends list who will do it and wait 3 days, that is normal standart rule from all companies, steam, blizz, etc etc
here the specific place to exchange FG versus D2R gift =>
