The requirements are:
- Purchase the blades at Walmart (between 3/1/12-3/31/12)
- Print off rebate form here
- Complete rebate form and mail in with original Walmart receipt with the price of the blades circled
The form indicates that you should receive a rebate within 6 weeks.
If you are in the market for good deals on sale items you might want to check over at LocoBuy
as they daily listings of good deals on a wide variety of products.
