What's the highest amount you've earned in a single day? Aside from dailies and selling items, what are your other money-making tips?

On average 3-5M when I get into doing my quests regularly. But when I get bored of questing, it drops to 1-2M.

Frankly I don't know what's the most I've ever earned in a day, but probably close to 70M, maybe more.

My best sP making tip is to do what you enjoy. If you "force" yourself to do stuff that isn't fun just to make sP, you'll eventually drift off and do other stuff avoiding the site, or losing the fun in playing. What's the point if you aren't having fun? So figure out what you enjoy, find one or two more profitable ways of doing those that doesn't take too much time. Then do those things regularly, followed by doing something that you really like but isn't all that profitable. For example I like playing games and I love playing Subeku, but I'm slow at the game and don't earn much sP when I play, so first I'll play a few games that are fast and profitable (like Caliph's Tomb) then reward myself with Subeku.

I can't recall the highest amount, but I think I make 500k-1mill because I can only be bothered to quest on weekends. I restock most of what I earn, so it's more of a passive way to make money. I enjoy the challenge though, and it doesn't feel tedious to me.

2-3mil from doing quests, then maybe another 50k-100k from selling quest rewards in my shop. Sometimes I’ll restock while I’m doing quests if there’s a big difference between the official and user shop price. The most I’ve gotten in a day from questing was 5mil; from selling 10mil.
