The Rock Climbing Club sent out an email this afternoon tipping its members off to a really sweet deal on Clif Bars. Amazon.com is offering bulk packages for $21.49, which is about half-off the in-store price. Better yet, if you enter the coupon code CLIFLUNA and buy two boxes, you’ll get $10 off and free shipping, saving a total of around $60 on your Clif Bars.

Even though there are no clifs near Columbia, the bars are perfect for mid-chem-lab snacks and sneaking food into Butler.
