Ex Input:
I grew up on orange sodas and thought this might be like a 'healthy' Crush. That would be a NO. Of course, tangerine has a bit of a different taste than orange as it's that much sweeter. Adding the carbonation to it just made it an unappealing fizzy, ultra sweet drink, not unlike cough syrup. Proceed with caution. Perhaps kids would find it super tasty.

With the Prime shipping, this made a great last minute gift. It seems a little pricey for the amount of fish, but the quality was good (according to the person I gave it to). In the end, I think this is better than a fruit basket or something similar.

I LOVE Popchips!!  These are the BEST.  Individual serving bags, flavors are great, taste is excellent.  My daughter and grandson love the barbeque.  I have found that buying them through Amazon is cheaper and Amazon offers the bigger bags also.  I have to watch that because I could eat the whole bag.
