Retailers purchase goods from suppliers or wholesalers in a variety of ways. They may place orders directly with suppliers, either through a sales representative or by using online ordering systems. Some retailers also attend trade shows or visit showrooms to view and purchase products.

Toothpaste can help reduce the appearance of minor scratches on a phone, but it may not completely make them go away. The abrasive nature of toothpaste can help to gently buff out the scratches, but it may not work for deeper or more severe scratches. It's important to use a non-gel, non-abrasive toothpaste and to apply it with a soft, damp cloth in a gentle circular motion. However, for more serious scratches, it's best to seek professional help or consider using a screen protector or case to prevent further damage. **

However, a standard toothpaste tube typically contains around 100-150 grams of toothpaste, which is roughly equivalent to 100-150 milliliters.

Ultimately, the margins for retailers are influenced by factors such as competition, pricing strategies, and the cost of goods sold. **
