Save up to 67% on some of the most popular products at GNC with the $3/$30 Sale through Tuesday, 3/11. I saw GNC Triple Strength Fish Oil 1500 Plus Phytosterols was one of the items included. It’s regularly $29.99! Some of the others that offered quite a bargain are the L-Carnatine, CoQ10 Soft Chews, and the Ultra Mega Green Vitamins. Shipping adds a flat rate of $2.99.
