A couple of tips...

With all of these internet coupons available to print you will go through ink quickly. Set your printer to default to gray scale and it will take less ink when printing them all. I have never had a problem with stores accepting coupons that are not printed in color. Internet coupons have individual bar codes on each one, so you cannot use a copier to make copies of them EVER! Copying coupons is considered coupon fraud and is the reason that more and more stores are not accepting them.

Also, feel free to use paper that has already been printed on one side. Retailers don't care if coupons are printed on the back of scrap paper. Just make sure to put the paper in the correct way so that the coupons print on the blank side of the paper.

Another helpful thing to do is to set up another email address that you can use to sign up for all the great deals available without getting lots of emails to your main account. You can get free email accounts through yahoo, gmail, hotmail and many other service providers.
