I have a plan and I want to know if one of these would work.

Plan 1I buy a 1 month gold account medal with sP Plan 2I buy 500 Cash Shop Credits and then use the cash shop to buy 1 month gold account medal

I want to see if the gold account is worth it first before spending real money.

Yes, you can buy gold medal accounts from users. Like in usershops/trades. You might want to also check the advertising boards. Usually they sell for around 7mill.

And buying credits with sP is also a good way to buy things from the cash shop without using real money :D

Ok thanks. I'm going to see which costs less for the moment.
