I just did one yesterday (it was a 2 day with Groupon) for Massage therapy (30 minute session) and sold 476, from the list about 95% are local NEW clients never here. Made about 7K gross, about 4k net after I pay my therapists
I have my tanning one coming out on the 27th, last year sold 309, this year hoping to come closer to 500+ as I too am adding custom
airbrush to the mix.
