Play time electronic games Store

Review Play Time Electronic Games Store, is one of the leading retailers of game products with more than 100 freestanding destination games specialty stores. We operated as a public company since 1990 and located in Houston, Texas. Now, In order to expand our business to meet the growing demand we decided to launch a website to sell DVD games online.

Review-continued The website is supposed to help customers create their own accounts and store their information for easy access every time they shop at the website. the customers can search for DVD’s and buy what they select, pay the invoice online and receive receipt that has a tracking number of the order.

Review-continued The customer can leave feedback of their experience and receive staff replies. The manager can interact with vendors and with staff to determine what new DVD’s should be bought . And also receive sales and inventory reports.
