Right now Kelly's Closet has a coupon code for a free diaper cover (guaranteed value over $13) with a purchase over $49. Just enter the code FLATSCHALLENGE at checkout. You can also get free shipping with a purchase over $49 (no code needed)! They are also offering double diaper dollars for a limited time, 2 points for every dollar spent! Points can be redeemed for store credit.
225 points = $10
500 points = $30
750 points = $50
1000 points = $75
They have great customer service and lots of product to choose from. It may be because I live in Maine (home of Kelly's Closet), but I have always received my orders very quickly. Lots of incentive to buy some diapers!
Have a great weekend and have fun shopping!
