I agree. As a marketing consultant I also find that business owners are not consistent with their social media follow through. 

That is one of the best places to place your product info and it is free!

Also they don't continue their marketing effort due to low marketing budgets. There may be new help on the horizon.

In the early days of my investigating drop-ship marketing the advice was for minimum 30% to be set aside for marketing. I would suggest talking a good look at that as that is the fuel to increase business, while you are learning the tip and tricks of lowering expense.

Check with me if you need help with how to promote on social media.

Also see where most of your buyers are coming from. Have some sort of record keeping, by age, gender, location etc. Then use that information to market further.

Because now you understand your target market better.
