You can stretch your coffee by using two filters next time you brew a pot. The coffee will come out richer and stronger and you can stretch your coffee grind much longer!
Pour used coffee grinds on your lawn, especially areas where the lawn is not growing well. The grinds make a great fertilizer.
Coffee grounds make a great body/facial scrub!
Sprinkle some used coffee grounds in the cat litter box for a natural deodorizer.
Keep some coffee grounds in a container by the sink to use for scrubbing pots and pans.
This one I have not tried, but I have heard it really works. Rub coffee grounds vigorously on cellulite areas while in the shower. Coffee is a stimulant and will break down fat deposits when rubbed on those areas.
