Kinda scared I committed coupon fraud.

This morning there was a post going viral of an otc misuse at walmart to get groceries for free. Everyone was using it, and being a family of 5, I took advantage of it too. This included creating a few accounts in order to get the coupons. Then applying to walmart to get the discounts. I did it and paid $12 for $230 of groceries. I didn't realize that it was fraud, thought maybe a glitch. But I found out now that it was fraud as they closed all the coupons. What will happen to me? Am I going to jail. I'm currently panicking
