A very good example:

 

For beauticians or other centers it is always difficult to buy the devices because the purchase cost is very high and in addition how to make it profitable ?

We sell the cavitation machine at the price of Fr. 4699,- instead of Fr. 24000,- at other sellers. How to make money in not even 1 month? Simply by offering on Facebook, by mass mailing and on your sales site and to your customers a study over 4 weeks ! You are offering 4 cavitation sessions for the price of Fr. 199,- plus Fr. 20,- administration fees instead of Fr. 880,- for 4 sessions. On Facebook and other advertisements, you can ask  "We are looking for 50 participants for our cavitation study." You have 50 registered participants, which gives you a turnover of Fr. 10950,- in just 2 weeks with a profit of Fr. 6251,-.

We wish you a pleasant day and see you soon ! My Marketing Consulting
