Well I got my reply from Marketforce. It appears the $50 limit only applies to people receiving paper checks. I asked for clarification from them: "I have direct deposit. Are you saying I don't need to reach $50 before I'll get paid and that the $50 minimum is for paper checks and gift cards only?"
HERE'S WHAT MARKETFORCE REPLIED TO MY INQUIRY:
"Hi, if you have decided to opt-out for direct deposit for your payments, we will soon be shifting away from a paper check to an electronic card payment (e-card). Once we have officially made this change, we will post an update on the shopper portal. In the meantime, you will receive a paper check if you do not elect to use our direct deposit option.
Once we change over to the e-cards, this is the way it will work: Each time we run shopper payroll for the respective month then you will be able to “request” a distribution for your payment. The request will take you to our fulfillment vendor and they will deliver the payment card electronically via email. However, you must have a $50.00, or greater, payment balance that is owed to you before you can request and receive an e-card payment.
Direct deposit is definitely the quickest and easiest way to receive your payments each month, so please sign up for direct deposit if you can! Thank you."
