EDIT: This rebate is no longer available.
A ton of people sent in this free Arm & Hammer Essentials rebate form, which from the look of the fine print, is a legit freebie offer. They'll send you $3.50 to anybody and everybody who buys their product, regardless if you enjoyed or hated it. It's a smart way to get your product in the consumer's hand and let it sell itself, but I'm not a huge fan of rebates. Too much work for me! I'm the kind of guy who never unties his shoes because those five seconds are far too precious to waste!
