Check your local Kohl's store for the 48 Count box of Green Mountain Holiday Flavors (French Toast, Eggnog & Gingerbread). Past their "use by" date but they still taste just fine to me.
They were marked down to just $11.99 then the cashier gave me the 20% off "Friends and Family" discount.
So - $9.60 for 48 K-Cups or JUST 20¢ EACH!
Didn't see any online.
