Your local spa is in the health and wellness industry. If they have been in business for a while they have a clientele that may well be interested in your offer.

There are plenty of opportunities to partner with spa owners who want to increase their customer base.

If you are selling a high ticket offer you could give away a free spa treatment when customers buy your services. 

In exchange, your spa could give you a deal on the services you buy to give away. 

The key to success here is to tap into their customer base by providing the spa an app they will gladly give to all of their customers who could be interested in your services.
