carried online (vs. in stores) I'm obsessed with the variety shown here: the Asiago & Cheddar Crisps, which are delicious. Dubbed "snacking made simple," their philosophy is that snacks should taste great and be part of a healthy diet. All their snacks fit into one of 3 categories: Healthy, Smart, or Crave. I've also tried the Sriracha Cashews, and those are pretty addictive as well.
One caveat: these snacks aren't cheap. If you end up liking them and want to try more varieties (above and beyond what Target carries) plus save some $, you might consider going directly to the source. Naturebox runs a whole "snack membership" program from their website, where you can buy in bulk and schedule ongoing deliveries.
