Can you complete the same audit twice? Field agent.

There's a Flash food App audit in my area. You purchase up to $20 worth of groceries in the app, and then pick them up at the grocery store. You're reimbursed for the purchase. I've already done the audit and have received pay for it, but noticed it was relisted. I'm just wondering if I do it again will I receive pay or will it be rejected for me having already completed the audit before?
