Every successful dealer has a story about the mistake that taught them the most. Here are the common ones so you can skip the expensive education.
Mistake #1: Buying Without Research
That "rare" item might be common, that "antique" might be a reproduction. Always verify before paying. Your phone can check prices in seconds - use it.
Mistake #2: Overpaying for Inventory
Enthusiasm leads to overspending. Set a maximum price and stick to it. If you can't at least double your money, walk away.
Mistake #3: Poor Photography
Bad photos kill sales. Taking an extra 10 minutes for good images can mean the difference between selling and sitting.
Mistake #4: Incomplete Descriptions
Missing measurements, unclear condition notes, and vague descriptions lead to returns and negative feedback.
Mistake #5: Ignoring Shipping
Underestimating shipping costs eats profits. Damaged items from poor packing destroy reputation. Master shipping or lose money.
Mistake #6: Holding Too Long
Sometimes you misjudge an item. Rather than letting it occupy space for years, cut your losses and move capital into better inventory.
Mistake #7: Not Tracking Numbers
If you don't know your costs, profits, and margins, you're not running a business - you're having an expensive hobby.
