Is street-level advertising a good way to get an audience for the business?

Hey, I own a car accessories shop. We had a good sale during the initial period, but eventually, the sales started to decline. I am guessing it is due to the high competitors in my region. So, I am planning to provide good offers to get my business back on track. But not sure to use what medium should I use to reach my target customers. I had previously done street-level advertising and has given proven results. So, Should I be following the same or do something different? Thanks.

Why not? If it has given you proven results, you can try it again. Or if you have ample budget, you can step up the notch and use interactive led displays to engage your potential clients.
