Oddly enough, Ive made quite hte fortune on the MB, despite the undercutting bots.
It's because bots tend to focus on low effort high demand items. Sell a 1000 units of a 500 gil item and if you have a bot that is constantly monitoring the MB, you can generate a profit. For a real world example of this, look no further than how Amazon Market Place operates. It is the same concept in real life. Competing shops selling hte same item and undercutting one another by pennies if it gets them the 'buy box'. They dont turn out much profit per item (Might even be pittance, like 50 cents a sale), but if you sell 10000 of it, that small pocket change adds up.
Rather, if you want to compete on the MB, stop trying to sell casual items. If you can gather it via a crafter, youre not gnona become ultra wealthy with it right off the bat. But rarer and harder items to come by, like those from Deep Dungeons or High end Crafted Gear, or mounts among other items is where you can generate a good profit. Yuo have to be paying attention to whats out there being sold and putting out a sale price that makes someone think "Gee thats a steal compared to other vendors."
Here's an example - The pegasis mount from PotD may sell for 15 million on some servers, but if you put it up for 13 million, It's likely to get snatched up really damn quickly. Yes, you lose 2 million and you are not min maxing your sales, but such a dramatic price difference lets the common buyer whos got the cash and no patience pick it up asap cause they see that as a huge steal compared to your competitors. You get your 13 mil right then and there, while competitors run the risk of their profits slowly being chipped away at by micro undercutters. To finish this anecdote, I sold mine for a 13 mil price point when the market average was 15.5. After two weeks, the market average was 8 Mil, and many of the vendors who had it at 15 mil were still selling it, but now at 8 and 9 mil price points. I abused other peoples price point to give the impression my sale was a bargain and came out ahead.
This is business 101. The whole idea that you need to not undercut big or stop adjusting your price point is silly. Yeah its a pain when someone undercuts you. Tough. That's how it works and there's nothing you can do to stop that from happening. Use your head, and gamble smartly on how you can push your sales. Taking 13 million upfront is way better than sitting on an item for 3-4 weeks watching the price point get chipped away until the item is half what it was worth at all because you couldnt bear to part with a million gil is silly. And stop blaming bots for not making a profit on the MB. Yeah, bots are an issue, but theyre not so prevalent that there is 0 way for you to make profits. Ive done it, fellow FC members have done it, friends I play with do it. You just have to be savvy about what works and what doesnt. High demand hyper competitive items that are easy to acquire arent gonna net you millions typically, bots or not. Anyways this was a tangent cause I do hate the "Muh Bots are making me poor" spiel that gets touted. Youre not making money on the MB cause of bots. Youre not making money because youre not playing the MB and doing your Homework to find ways to make money.
