Thats $21 per 200g box free shipping tax included
Also I ordered two 160g buckets. The 200g is not on sale but the 160g buckets are. Buy two and get 30% off. Sometime you can stack the 15% off $50 which I did for in store Pickup. Check out with Paypal because somehow the coupons is having errors if you sign in and use your CC. 15% store pickup coupon are usually available during the weekends on their website. Still cheap but not as good as the 200g box deal
