I know that buying up autopriced cheap items to sell them for more is, if not against the rules (I'm not sure) heavily frowned upon. What do I do if I find one of my items has been mispriced?
For example, I went to autoprice my shop today and a 1.2 mil item is selling in shops for 120k. It's clear where the mistake happened, and there are about 8 mispriced items. What should I do? I just left my item at 1.2 mil. I want to buy up the others but that seems iffy in terms of taking advantage of people.
What do you do when an item you have is clearly mispriced in shops?
You're not breaking rules correcting prices of your own items.

But it seems like the only way to correct the price is to buy out the people who mispriced it! That itself seems iffy.
You don't have to buy anything up that you don't want to, just correct your own price.

Right but no one will buy it at 1.2 mil when they can buy the others at 120k.
That's a pretty egregious one. In a case like that, if the higher price really seems like it should be the "correct" one and it's not just wishful pricing that's due to drop anyway (e.g. a token shop item vs. a newly-released restockable), I'd try to see if I can determine which shop originally undercut by that much (usually it's obvious because the whole shop is full of way underpriced things) and if it looks like an accident or misunderstanding of pricing etiquette on the part of a newbie, I'll send a polite smail to them suggesting that they check their prices and not undercut so drastically. If it's just one or two that got severely auto-underpriced, I've also bought them all and contacted the sellers to offer to sell back at the price I paid (I've always just had them say to keep it but I don't feel right not offering). If it's more than I want to invest in, I might just let the sellers know without buying them. If a shop chronically undercuts and it's clear that it's intentional, I just buy all their stuff and resell it for profit. I don't know why people do this but I've caught several shops like this and it is frustrating.
Usually in these situations, it's not THAT far off and I'll just buy up the mispriced items to frag or resell. I'm not gonna bother smailing 20 people for a few thousand lost sP each, but yeah, if we're talking millions I'd want to let them know.
Thank you for the input! This is helpful. This one is 1.2 mil down to 120k so I think it was someone mistyping for sure. It's a Morostide food item. Maybe I'll just buy up the 120k ones and put them in trades for the people so they don't get bought up by someone to resell!
yeah if it's an extreme difference and doesn't seem to just be a natural drop from an overinflated value, you could message/comment the users whose shops have the item underpriced and let them know what's going on so they can fix the prices if they want to.
and no, it's not against the rules to buy up underpriced items to resell at a higher value. you can buy any items for sale at whatever price they're set to, and even if someone messages you asking for it back because it was underpriced, you're not obligated by site policy to return it (though it would probably be the nice thing to do if it was a really significant difference); you can set your prices to whatever you want, and if people buy the item at that price they buy it, and if they don't they don't.
intentionally bottlenecking the market to take advantage of autopricing users is also not officially against the rules, but it is something staff would like to look into if they find someone consistently doing it—but of course this is hard to actually track and prove it was done with malicious intent, so it's kind of a gray area.
Thanks so much for the clarification! I appreciate it :)
Ooh, and happiest of birthdays!!!
