I haven't tried this yet to verify but I know multiple people who did use this deal. Walmart has Holmes Air Purifiers for $14.94, use $10 off Holmes Air Purifier Coupon and score one for $4.99!
If the page does not direct you right to the page the coupon is on: click on the "personal care" category and find the $10 off coupon, DO NOT try using the $20 off coupon with this particular deal :)
