Mrs. Fields is giving customers an excuse to eat cookies all day long on National Chocolate Chip Cookie Day on Tuesday, August 4, as well as before and after.

The cookie bakery chain is offering 20% off all eligible items sitewide on its website from now until Saturday, August 15 by using the code CHIP20. The deal covers everything from cookie cakes and cookie tins to brownie bites and Belgian chocolate-covered berries.

“Since 1977, Mrs. Fields has been creating gourmet chocolate chip cookies, cookie baskets and gifts,” the company says. “This year Mrs. Fields is very excited to celebrate National Chocolate Chip Cookie day by extending 20% off our online treats so that cookie fans everywhere can send themselves, or a friend, delicious chocolate chip cookies.”
