im a 3rd age merchant, ill try to explain geez..
so you havve you fucking loaded account, a 3a ammy trade price is 24m. in world 2, people sell the ammys for about
70m not 30, anyways. you buy the ammy from the seller, you pay 70m cash, they give you the ammy and they give you a unch of junk.
Main:has ammy and tons of junk
now your main has the ammy, its street price is 70m, and you can sell it for that ammount, but its trade price is 24m.
Pure:has 24m cash
you multi log, your main sells your pure the ammy for 24m, then you go on your pure and sell it for 70m. its not the best way but if anyone wants to do this just give me a pm, i know ways of getting rid of junk. (example, buy a bandos plate for 10m cash and some junk, and then sell it for 11m, people actually do this. and some junk is better then others, try to get dragon stones, make glorys with assist, and sell.)
and if anyone needs proof i know what im talking about, i will show you my 3a mage top and bottom in rs
conclusion: for your every day transfers, stick with BH. this is best if your pure has alot of junk...(Every pure needs 99 fletch, why not get it with maple longs (u) )
