Need Help - Makeing RSGP

I Need help, I need to know how to make money on F2P. Either by merching or a skill that will make me money.

I only have like 500k atm, rest of my money is in members items in my bank


What is a good item to merch?

 

I think rune scimitars are still pretty good to merch on F2p.

 

Buy vials, fill them up and sell them.

 

Would be pointless? I would only get like 10gp profit per one vial.?

 

I used to merchant trout in F2p, Buy it for the min, and sell it for max. I had up to 3m Trout circulating through bying and selling. It's easy cash. Well it used to be, i'm not sure how it goes now.

 

Alright, Ill try this then, thanks for the help.
If this doesn;t work im just gonna get big bones and Limps and sell.
