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.
