Good offline work is not easy.. If you're already doing some of these things mentioned above, then you're off to a good start. Cold calling, Newspaper ads and FLYERS on windshields work like a charm. Don't forget postal mail.. Postal mail is also very effective and there's no law against it. Do it right, and work hard and it'll pay off; however, there are some things that must be taken into account such as name branding, hours of operation, customer service, and store location.. These things are very important; and if left unchecked can be a failure from the start.
A referral system is also very important. Along with a referral system, send coupons in your postal mail outs. They'll eat it up if you send them a warm up letter with the referral system, and then the "coupon" in the second mail outs. Space your postal mail outs by a couple of days but never let them get cold!
If your autoparts store offers some kind of service, then you should follow up with your existing customers who have made a purchase (be it accessory, OR service)
Contact them like this: From sales dates, after the third day, then 15th day, then 30th day, then 60day.
After the THIRD call and you've developed rapport with them, (30 days from first sale) ASK FOR A REFERRAL.
"We have a referral program "which consists of...(short and sweet!)" Is there anyone you know that would like to "take advantage of incentive?" It could be an incentive like, bring a friend and get a free oil change, or X percent off your next purchase or service rendered. Sound as natural as possible and expect a few "no" but if you work this system I've outlined for you, you'll be on your way to success. Good luck!
OUTSIDE the BOX : Send mobile phone sp4m via BLUETOOTH to a mass number of individuals at existing autoparts shops, racing venues, festivals, and anywhere else you can find cars.. Pass out flyers on windshields at these same locations. (EXCEPT for existing businesses, we send sp4m to those places rendering AUTO services as well, but we shouldn't pass out flyers for your business at auto-z0ne! Everywhere else is fair game.)
Tip: Customer retention is KEY to your referral program. Your auto parts store should have a good customer service department or you will NEVER get referrals. You can also ask for referrals after you've helped; even if you only answered a few questions via telephone during your follow up calls.. You can ask like this, "Now that I've helped you, will you help me?" You will always hear a yes on this one. Now, tell them about your referral program. You can also ask for their friends' name and phone number.. Remember, you're helping them. So, neither party has anything to lose. If they refuse to give up their friends' number, then respect that and politely ask them to call their friend, so you can give them X incentive (short and sweet.)
I hope this helps. Take care!
