This is our preferred clam chowder . We like the natural taste with lots of potatoes. The only complaint is I think the soup can be creamier. Amazon has much better price on this with subscribe and save.

Switch tastes more like chemicals than juice. I was expecting something along the lines of Orangina, instead it's closer to orange soda but without the carbonation level that makes orange soda enjoyable. For a small drink (8.3 oz), it's pretty high in calories (140). Frankly, I don't think the flavor is good enough to justify the caloric level.  Bottom line: If you're die-hard soda drinker, this might be a better option for you. If you're a die-hard juice drinker, stick to juice. If you want fizzy juice, add a little seltzer to your fruit juice.

I like these crackers.  Or, at least I'd like to like these crackers.  They taste like "normal" crackers, and they crunch like "normal" crackers.  But they aren't "normal" crackers.  They're very fragile, and it doesn't help that they are packed in a foil bag rather than the sleeve-type packet common to "normal" crackers.  Most of these will be broken before they ever get to you.  My all-time high is four completely unbroken crackers in one box. A few are just broken in half but most are broken in many pieces.  Don't count on finding enough unbroken crackers to serve to guests.  It's a shame.  They could be good crackers, but this is too much to pay for cracker crumbs and pieces.
