on sell

on sell might be a casual way of referring to items that are currently available for purchase or promotion on online platforms like Amazon. When products are “on sell,” it often means they are offered at discounted rates or during a special campaign. Sellers use this tactic to boost visibility, clear out inventory, or compete in saturated niches. Running successful promotions can lead to increased reviews and better rankings, ultimately helping grow long-term profitability through higher conversion rates.
