1.  Send out communications to steady customers to remind them you exist; whether it be an email newsletters, reminder card or holiday greeting, written communications remind them that you exist and acknowledge that you have not forgotten them.

2.  Meet customer needs and expectations.  When a customer is treated well, they will remember it.

3.  Being loyal to employees will inspire them to pass that loyalty on to the customer and the customer to pass it back to your company.

4.  Train employees in customer relations.  Teach them how they are expected to interact with your customers and encourage them to help the customers.

5.  Offer incentives that provide a reason for customers to return, such as a member card that makes their eighth oil change free.

6.  Make sure that you have the items that your regular customers purchase in stock and that your employees understands the products you offer.

7.  Be reliable and consistent.  When you promise a customer a delivery on a given day, deliver on your promise.  However, you cannot control everything and if a mistake occurs, compensate your customer by providing a discount for the inconvenience.

8.  Try to accommodate your customers as well as possible.  Upset and unhappy customers are not return customers.

9.  Offer people rather than technology to deal with complaints. 

10.  As cheesy as it sounds, people want to be a name, not a number or a price tag.  So remember your regular customers' names if at all possible.  This will make them feel important to you and your organization.
