I've read the reviews and I agree that Yuban is absolutely the best coffee but at $100 for 12 cans comes to over $8 a can.  That's $3 more a can than I pay at my local store.  I don't understand the high price?

Found these while looking for good, cheap, low-calorie snack packs to buy in bulk for my office.  After my first shipment, I decided to have two boxes shipped to the office monthly via subscribe & save.  My next shipment arrives in two days. I'm so excited!  Gotta have my pop chips...

I cannot say how much I love Kettle brand potato chips. Kettle brand has a large variety of unique flavors, and the quality of the chips themselves blows all other potato chips out of the water. The ingredients list is printed on each bag and the only thing really bad for it is the oil they are frying the chips in. I love that these aren't filled with nasty chemicals. I ordered the cheddar and sour cream krinkle cut ones which are great but I was torn between the <a href="http://www.amazon.com/gp/product/B0048IFUSC">Kettle Brand Potato Chips Fully Loaded Baked Potato, 2-Ounce (Pack of 24)</a> and the Jalapeno flavor. While I know the jalapeno flavor is good but this is way better. They include liquid smoke instead of actual bacon which I'm fine with since I've a vegetarian. I ordered this to give to guests coming from out of town for my wedding this spring and I can't guarantee how many I will have left. My fiance and I love these. The packaging is perfect for anyone who is giving these to kids to take for school lunches, or handing out in gift bags, even just for portion control.
