Shutterfly Birthday Codes

Shutterfly.com: Get $10 off with code MARCH10 (3/11). Enter a photo of any birthday celebration and get 25 free 4x6 prints just for entering their Birthday Celebration Contest. Top prize is $1,000. Free shipping on $30 with code SHIP30. The email I received about the $10 off code MARCH10 did not specify if it required a minimum purchase. YMMV.
