Nowadays, the wishlist is a common feature offered by many online stores which increases the sales by some percentage. The users can save some items on their wishlist and when the price is lowered down they can purchase the product. This is very convenient for both the store admins and the customers. The admin has the power to see the products which are currently placed on the wishlist, so they can understand the customers.
