EverydaySource cuts 10% off orders of $10 or more via coupon code "MHALLOWEEN2012". That's the best percent-off discount we've seen from EverydaySource in recent weeks, although we saw 10% off sitewide with no minimum purchase required in August. Shipping starts at $2.99. Coupon ends October 31.

A best bet is the Snap-on Rubber-Coated US Flag Case for Samsung Galaxy S III (pictured) for $12.49 before the above coupon, $11.24 after. With $2.99 for shipping, that's the lowest total price we could find by $4.
