In case you haven't heard, Burt's Bees is running two nice deals right now through the end of May:
First: free shipping on all lip products, no code required and no minimum order required. Also, when you place a lip product in your cart, an instant coupon for $1.50 off will appear and you'll automatically get the $1.50 deduction at checkout (one coupon per order).
Second: All towelettes are 20% off, no code required. The discount is automatic.
Unfortunately, you can't combine the two offers (I tried adding a lip gloss to my cart and a pack of towelettes to my cart and I was charged $5 for shipping). However, when I deleted the towelettes from my cart, shipping was free. But if you're planning on doing a major haul and it includes more than just lip products, you do get free shipping on orders of $49 or over.
Again, both of these deals are valid now through May 31st on the Burt's Bees website.
