I love these - they taste great.  But I get them in the local Dollar Store. Two stars for the value, five for taste.

I ordered the disposa kups with the thought of making my own kups. They don't fit together without a big production. The lids won't fit and water comes out the top of the brewer lid as well as the kcup. Just a big mess. not what I wanted at all. want to return them and get a refund. Donna Phillips
