There are a lot of pop up ads on the Internet at the moment for "Beauty Products" like Dead Sea Beauty Kits where free samples are being offered on trial, or even more insidious "Testers wanted". Don't be tempted, after you go through the process you will be asked for credit or debit card details so that you can be charged for post and Packaging. At first you will be charged an item of around £3:99 or some other small and apparently reasonable amount, then a month or so later you will start getting larger amounts up to £90 debited to your account, and it is apparently very difficult to get them stopped.
I understand that it is possible to get the payments stopped, but it is a lot of hastle and getting refunds is even harder, so be warned, don't be fooled. It is a shame that this sort of scam always preys on those who are most vulnerable and often can least afford the loss, the temptation to get something for nothing is even stronger when you ave very little. Remember if it seems too good to be true, it probably is.
