What are the activities in merchandising?

Merchandising Activities
Merchandising means selling products to retail customers. Merchandisers, also called retailers, buy products from wholesalers and manufacturers, add a markup or gross profit amount, and sell the products to consumers at a higher price than what they paid. When you go to the mall, all the stores there are retailers, and you are a retail customer.

Retailers deal with an inventory: all the goods (products) they have for sale. They account for inventory purchases and sales in one of two ways: Periodic and Perpetual. As the names suggest these methods refer to how often the inventory account balances are updated.

The activity of promoting the sale of goods at retail.
Merchandising activities may include display techniques, free samples, on-the-spot demonstration, pricing, shelf talkers, special offers, and other point-of-sale methods. According to American Marketing Association, merchandising encompasses "planning involved in marketing the right merchandise or service at the right place, at the right time, in the right quantities, and at the right price."
