Amazon is offering a special deal on Luna Bars.
Save $10 when you spend $39 on Luna Bars at Amazon. Use code BARS4ALL at checkout. (expires March 31) I think they are selling out pretty quickly. Other bars, such as Clif Bars, are also included in the deal.
You can also save an additional 15% by setting up the new Amazon subscription where they will auto-ship Luna Bars to you every month. Subscription items ship free.
