Hi purple doll. When seeking a provider for Coolsculpting, look for the advanced training certification (Coolsculpting University). A plastic surgeon's office will provide onsite expertise, and discussion comparing liposuction to CS will be possible. A provider that has multiple machines and the latest applicators is a sign of a busy and experienced CS office. Now you can get Brilliant Distinctions points to provide money towards other services (Botox, Fillers, Latisse, SkinMedica products, etc), but not all CS providers offer this. (Also, the company that makes CS machines has set a minimum charge that practices are supposed to abide by to avoid losing their company support. ). If you find all of the above qualities with a Groupon, go for it---you will get what you pay for. Best wishes,
