It is the end of the month, and that means that the coupons on online sites will be changing. If you are interested in any of the coupons that are available now, you should go ahead and print them. They might not be there starting May 1st, or the coupons might reset on May 1st and you'll have the chance to print them again. Don't go crazy and print off all the coupons (you'll waste paper and ink), but I would suggest looking through the sites and printing off any coupons that you KNOW you'll use, and also any high value coupons that could get you very cheap to FREE products. Here are the top three that I would suggest looking at:

Coupons.com

Redplum.com

Smartsource.com
