Not worth the $$ in my opinion

Decent Snack, But Not Worth the Price
Flavor Name: Green & Kalamata, Size: 4 Ounce (Pack of 5)
Decent Snack, But Not Worth the Price I was intrigued when I watched Freestyle Snacks on Shark Tank, especially since I really enjoy olives and loved the idea of having a convenient, on-the-go option. I’ll admit..., the packaging is excellent. It’s clean, well-designed, and makes it easy to toss a pack into a bag without worrying about spills or mess. That said, the cost outweighs the quality. The olives themselves are nothing special, and certainly not different enough to justify the premium price point. You can buy similar (or better) olives at your local grocery store for a fraction of the cost and portion them into zip-top bags on the days you want them. I would be a regular customer if the pricing were more reasonable, because the convenience factor is definitely there. Unfortunately, as it stands, they’re simply overpriced for what you get.

Delicious!
Flavor Name: Original, Lemon Garlic, Hot & Spicy, Size: 4 Ounce (Pack of 3)
Absolutely frickin delicious! The size is good for what you get. I use a bag 3 times for salads. Very easy to keep in the fridge and open and close. I think compared to jars and other olives and the quality it is a good price. The flavor is awesome!
