I found this deal on the Lowes site. It looks like the Lowes rebate is for $4 back on 4" Filtrete filters.
Another link shows. Get $6 Back on Filtrete 2-Pack Air Filters
Get $6 mail-in rebate with purchase of 2 or more qualifying 3M Filtrete Extra Allergen 2-Packs. Offer ends 6/30/2011. When you click on that link it brings you to the $4 rebate form.
