CONGRATS @jazzyvar84 on your Belk Credit Card approval!
Congratulations on your approval! Your card will grow over time. You probably have the store card as I believe you have to have at least a 700 FICO score for the MC from other posts I've read. When mine was approved, it was $300 and is now $5500. I use for the flex pay all the time.
Flex pay is plan where you get 90 days no interest to pay off purchases. I always wind up chargung a couple hundred everytime i'm in there, but I think the minimum purchase for flex pay $150. I usually get an increase every 6 months, but it's a Synchrony account, you could hit the CLI button after your third statement.
