NPC quests is good, but what else?

probably the wrong place for this

reselling ^^ i used to do this until i got lazy and now im broke like a joke

Selling expensive items like boosters, amulets, and holiday-themed items can make you rich. It takes a few months to accumulate the amulets and boosters but it's worth it in the long run.

quests are the easiest/quickest way IMO, but restocking is p easy here, i would start at the food shop for beginners, almost anything in there sells way higher in user shops than in the shop itself.

If you can purchase cash shop credits you can resell them for a nice amount of sP in form of gift cards.

Apart from that just save and don't spend your money on clothes or whatever until you have reached your goal.

Charge a fortune to Darkside refugees trying to get into Centropollis. They will give you their first born for a free pass in a makeshift boat and a lifejacket. Rinse repeat

My forum title is proof the technique works. Don't listen to peasants who will suggest you go play fetch for a bunch of lazy NPCs.

And I thought it had to do with skills, patience, and DETERMINATION! D:

Oh, and I forgot about the luck factor too. I'm still waiting for Calvin Blackmoon to raid Sebastian Phoenix and drop billions of sP on everyone :)

I'd love that! Time for a plot?
