1. Stop Using "Buy Now" and "Sell Now"
The most common rookie mistake is impatience. Using "Buy Now" or "Sell Now" may seem fast, but it almost always costs you extra Stubs.
The Fix: Use Buy Orders and Sell Orders instead.
To Buy: Place a Buy Order 1 Stub above the current highest bid. This pushes you to the front of the line without overpaying.
To Sell: Set a Sell Order 1 Stub below the current lowest listing. You'll sell faster while keeping the maximum profit.
2. Don't Forget the 10% Sales Tax
Every sale in the Community Market comes with a 10% transaction tax (https://www.u4n.com/news/10-tips-for-mlb-the-show-26-community-market.html). Many players forget this and end up losing money on small flips.
How to Avoid Losses: Always calculate your net profit first.
Net Profit=(Sell Price×0.90)−Buy Price
If your margin is too thin, the tax could turn a potential gain into a loss.
3. Avoid Buying During Hype Cycles
Prices spike after big real-life performances or when new programs drop.
The Mistake: Panic buying or giving in to FOMO (Fear of Missing Out). Cards purchased at peak hype often drop in value shortly after.
The Strategy: Wait for market dips or flash sales. Patience pays off more than rushing into a hot card.
4. Don't Ignore Your Inventory "Trash"
Some players focus only on player cards, forgetting about duplicates, equipment, or stadiums.
The Fix: Perform regular inventory cleanups.
Sell unused equipment, stadiums, or sponsorships.
Diamond and Gold equipment often retains high value, especially early in the game cycle.
Clearing inventory frees space and adds extra Stubs for future flips.
5. Respect the New Buy Limit
MLB The Show 26 now limits purchases to 20 per item.
The Mistake: Attempting to hoard hundreds of one Bronze card hoping for an upgrade is no longer possible.
The Adjustment: Diversify your investments across multiple cards. Focus on flipping multiple players rather than trying to corner the market on a single card.
6. Use the Companion App Wisely
The MLB The Show Companion App is crucial for staying on top of the market.
The Mistake: Only managing the market in-game. This leaves you slow to react to price changes during work, school, or other offline moments.
The Fix: Use the app to monitor your orders, re-list cards, and adjust prices anytime. Staying proactive keeps you ahead of the competition.
Final Tip: Successful Community Market trading is all about patience, planning, and consistency. Avoid these common mistakes, and you'll steadily grow your Stub balance while building a competitive Diamond Dynasty team.
