I have, but it has been a long time. I remember their surveys as being very redundant, but not difficult. Payment was made with a reasonable period of time. They are neither the fastest nor the slowest companies to pay.
They have always paid me on time according to their stated terms: "All shopper fees will be paid through PayPal by the end of the month for the previous month's assignments. In most cases, the payment will cover all completed assignments received and invoiced to Beyond Hello's client during the previous month. In the event you do not receive full credit for any item which you purchase with your funds at the direction of Beyond Hello (the "Funds" Beyond Hello will reimburse you via PayPal for such Funds and any sales tax associated with that purchase provided you deliver to Beyond Hello the undamaged item and sales receipt."
I am working for BH and like their jobs....pay in 2 months with reports being a bit long and redundant. They have a CA great coffee house I enjoy with decent pay. They do have age requirements on their retail shops, but they are a solid company.
