This place is legitimate. If you qualify and you go in for a market research focus group, you get paid cash money. One time I got like $200 for 2.5 hours. It all depends on who their customer is. They do not call your number unless someone from your number solicits them.
Called, didn't leave message. Have called before, asked a couple of quick qualification questions to see if you qualify to attend a targeted marketing participation group. I didn't.
The number is from Perryman & Kroll a firm that does taste tests on food and beverages and various other tests located in Dallas Texas @ Independence and Parker Roads - they pay you various amounts for your feedback/survey.
