This weekend, Shutterfly is offering $10 off ANY $10+ purchase (including sale items) when you use the promo code OURFAVORITES at checkout! Note that shipping varies depending on what you purchase and the $10 promo code cannot be applied to shipping costs.
As one idea, mouse pads are on sale for $5 each so you can get two free mousepads after the code OURFAVORITES at checkout and just pay shipping!
