Head over to Coupons.com to print this really high value coupon for $1.50 off Sunsweet Prune Juice Light. The coupon mentions a lot of stores, I am pretty sure Walmart will carry it also. The regular prune juice is $3.48 at Walmart so this will probably be close to that. I think this is under many Zip Codes but I know it is under 77380 for sure. Click the “Beverages” tab.
