Ultra ketone/ketone slim XT scam

Another scam promising that your excess weight will evaporate away if you take these magic tablets. I'm not going to link to the site. But this is what they claim their pills will achieve. How can people be so gullible?

 Same tired old stuff, raspberry ketone, and a laxative. Same old tricks laid bare in the terms & conditions. If you don't cancel your subscription pretty much immediately you will be charged £95 for what they told you was a "free" sample. And once in you're in. "Customers enrolled for a Subscription will automatically receive a 30 day supply of the Product approximately every 30 days, without any further action on your part. As consideration for each 30 day supply, we will charge your credit/debit card the retail purchase price amount of £99.95"
If you really want to try this stuff you can get it on line for less than £4 for a month's supply. So save yourself  £95 a month. Better still save yourself £99 and don't buy it at all. It's worthless ineffective crap.
