Platitudes in ads. There are some beauties out there, but topping the chart has to be, "qualified and knowledgeable staff".
Its a wild assumption, but chances are that quite a few of your customers have used the internet and are pretty knowledgeable themselves.
Qualified and knowledgeable staff, 25 years in business, lots of free parking gives the consumer not one good reason to shop at your store.
Ask your customers why they shop at your store and see if you can find a theme. Use that information to craft an ad you can shout about.
