CHewy’shas buy 3 get 1 free. Just got 4 boxes (200g/ea.) for 162 before tax. Incredible price. Bought the 4 boxes than also signed up for auto ship for additional discount. I dont recall the last time I paid 40.50 a box before tax. Hurry as it’s a limited time offer and if you don't have need or cash for so much salt at once, its worth teaming up with fellow hobbyist friends.
