I've found that with the saturation of retail on social media sites in general, the best way to make a sale is to target the right people who are already looking for what you offer...

For you: I'd recommend using highly targeted Facebook Ads (Target by age & gender plus any other things you know about your audience/buyers in terms of things they are interested in). You might also research companies who provide holistic relief for hot flashes, find their facebook pages and create a filter for your ads to target fans of theirs. You could see a HUGE return on just $100 Facebook ad buy.

Good Luck and let me know if you'd like to schedule a follow up call; I'd be happy to walk you through the setup and some additional strategies!
