Example Input: I thought these would be the perfect answer. Sadly, I guess the pressure with which my Keurig machine shoots the water through the k-cup is too much for the disposa cup, because every single time I tried it, coffee grounds were spewed up through the tiny hole in the lid of the disposa cup all over the inside of where the k-cup sits in my keurig. And yes, I used them properly.  So the issue, at least in my Keurig machine, seems to be with the lids. Some have suggested its a design flaw with the Keurig machine. In either case, these disposa cups were NOT the answer for me.  Biggest waste of money ever. I cannot recommend.

Example Input: 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...

Example Input: I feed my two Pugs and occasional rescue Newman's Advanced Dog formula. I like this better than the regular Newman's, because it has less ingredients. I supplement with high quality can food, organic free range chicken, healthy powder and salmon oil. My boys are healthy; their coats are amazing. Highly recommend but with supplements--see above.
