Use bot to make zeals then spend them on Magic exp.
Tho if you're alching, I would advice to visit this link: http://runescape.wikia.com/wiki/Alchemy_Guide
It's alchemy guide, you can see profit/loss from alching there.
Don't know much about whats the best item to alch but I usually stick with maple longbow (u)'s. You lose a bit but they're relatively quick at being sold in the Ge.
Yeh, I used what manic posted a few times but now my main got banned im on my skiller . But I was speaking to some guy alching at GE and he was alching arrow shafts and he said he was making profit...
