Starting on Sunday, select Glade air fresheners will be on sale at Walgreens. We often see deals for free Glade Scented Oil Warmers, but rarely do we have deals on the refills. Here’s a deal for you! Scented Oil PlugIns refill two-packs will be on sale for $4.99. Buy one and earn a $1.00 Register Reward at checkout. Use a $1.00 printable Glade coupon and redeem a $0.75 Ibotta offer. The final price will be just $2.24!
