Red Plum is celebrating National Coupon Month (yes, apparently we get a whole month to celebrate coupon usage!) by having a special Dash for Deals promo. What's the Dash for Deals? According to the Red Plum press release, "one deal a day will be hosted at www.redplum.com/dash featuring printable coupons, coupon codes or samples."
Earlier this month, I saw Amazon Student membership - free two day shipping for six whole months. This site may be worth keeping an eye on during September.
