I just ready this in an email, a job offer which requires some PI work!...with the following disclaimer:
"To complete this shop, a $50 deposit is required to cover the cost of the GPS tracker. The deposit must be sent through PayPal to firstname.lastname@example.org. The deposit will be refunded after the report is finalized. After making the payment, please email your Transaction ID to the contact information below."
Lemme see here....pays $30, but I have to deposit $50 which I "might" get back, when my report is finalized.....
