We tried these chips because DR. OZ had recommended them on his show as a healthier potato chip alternative.  My whole family loves them, we have not found a flavor that we don't like.  These are WAY better than any baked style chip.  Try them and you won't be disappointed!

Ordered 2 cases on different dates and got them within 2 days. Cant find these in the stores so please keep them in stock. Make for a great meal with some veggies or a salad...and this type of fish with omega 3's is good for you.

I ordered the hot cocoa for my grandson for Christmas.  He loves the flavor and is able to make it on his own.  Delivery was good, I had it in several days but still in plenty of time for Christmas.  Would recommend to anyone.
