Salt & Vinegar is my favorite, followed by those lime Tortilla chips (amazing with guac), and occasionally I get a real hankering for KC Masterpiece chips.
The best pretzel snacks are even better than that, since we have a Snyder's factory & distribution center a few exits over and they make so many good things. I get sad every time I see any, since my doctor has me off gluten. Their buffalo and honey mustard and onion flavors are crazy good... it seems they are doing gluten free now too, so I'll have to look for those.
Just had some Japanese chips delivered, those Chip Star stacks in Purple Sweet Potato and Pumpkin and they blow Pringles chips out of the water.
For popcorn, I just make my own 99% of the time so I can control the additives, but TJ's has Popcorn in a Pickle which is really good if you like both and Werther's makes a caramel popcorn that is flat out dangerous.
