SELLERBITES INBOX

An Amazon seller (OP) asked: How can a product go from selling out in a week to not moving a single unit?

Their story started like every FBA dream come true. 

• OP shipped 36 units of an eye care product to Amazon, sat back, and watched them vanish in less than a week. 
• Clean, quick, and profitable, the kind of result that makes you believe you’ve cracked the code.

So OP did what any confident seller would do: doubled down. Actually, multiplied down, 320 more units, roughly $8,000 worth. 

Same product. Same listing. Same Buy Box. Even the price was lower. 

Yet somehow, OP’s listing flatlined. Not a single unit moved.

🌀 Momentum mysteriously stalls

Sellers in the thread scrambled for answers, each theory wilder (and more plausible) than the last.

• Vanished visibility. Some said it could be a temporary listing suppression or one of Amazon’s “quiet” algorithm shifts.
• Stock in transit. Others suspected the 320 units were still mid-transfer between warehouses, technically “available,” but not yet fully sellable.
• Ranking reset. Once a product goes out of stock, it can lose sales velocity, dropping it out of Amazon’s search rotation. 🔃
• Saturated competition. Fresh sellers flood in, prices spiral down, and Buy Box share evaporates faster than your margins.

But a few sellers insisted it goes deeper, that Amazon’s system doesn’t just follow logic; it controls it.

🧩 Inside Amazon’s invisible hand

Veteran sellers didn’t hold back, offering explanations that ranged from algorithmic fine-tuning to full-blown marketplace manipulation.

• The algorithm effect. Restocking may trigger a recalibration period where Amazon “tests” demand again before restoring visibility.
• Logistics lag. Even when stock is “live,” scattered inventory can cause shipping delays that nudge you out of the Buy Box. 📦
• Competition churn. New sellers in ungated categories create price chaos — and the algorithm loves chaos.
• The cynical theory. Amazon’s AI could be spreading sales across sellers to keep prices low and ad budgets high, optimizing for Amazon’s profits, not yours.

🪞 Facing the unpredictability

Nobody cracked the algorithm, maybe nobody ever will. But one truth holds: momentum is temporary. Smart sellers restock conservatively, monitor performance shifts, and never assume success repeats itself.

Because on Amazon, predictability isn’t part of the Prime package.
