Money is tight, and we love our morning coffee. I found a way to save 50%. I find the brand name on sale, and buy the darkest roast (look for scale on tin). Brew a full batch of coffee, pour into pitcher. Then fill reservoir with water again. Using the same grounds, brew again.
This month's Consumers' Reports magazine gave 8:00 coffee their 'Best Buy' rating. I buy it at the local grocery store, though different stores have different varieties...I like strong coffee and find the Italian Roast does well for a thrifty price. Try the regular blend and if it's not to your taste, move up to the French or Italian (darker/more bitter) roasts. They also make hazelnut and vanilla flavored coffees. Whole bean or ground.
Coffee grounds that are left in the maker day after day and reused can mold can make you ill. This is a page about warning: don't reuse coffee grounds day after day.
