Folgers makes K-Cups for Keurig coffee makers, and they are available online on the Folgers website, Folgerscoffee.com. They are also available for purchase on the Keurig website, Keurig.com.
These sites allow you to sort coffee by roast type, among other options. Folgers K-Cups include some gourmet flavors, such as hazelnut cream, vanilla biscotti and sugar cookie. They also come in more standard flavors, such as Colombian, classic roast and French roast.
Most of these coffees are available in either 24-packs or sample packs. The sample packs contain five K-Cups and retail for about $4, as of August 2015. The 24-packs retail for around $11-$15, depending on the flavor, as of August 2015.
