You can get bulk coupons on Ebay

I've been doing this for over a year and thought I'd share. If you buy a lot of any particular item, check out Ebay for coupons. Usually, you can get 10-20 coupons for a couple of dollars and save. The only thing to be careful of is checking the expiration date and allowing about a week for delivery.

It has helped me save a lot of money on staples like cat litter, coffee, tea, etc. On average, I'll spend 2 dollars for 20 dollars or more in savings.
