When I go to Dollar Tree I always take my coupons with me because you never know what you may find. I ended up being able to get 3 full size Pantene Hairspray for free. They were priced at $1.00 but I found 2 coupons. The first is for a $1.00 off one. The second was for $2.00 off two. All I ended up having to pay was the tax. This was our closest location in Perrysburg, Ohio so your store selection may vary. I am pretty sure both coupons expire on 4/30.
Fyi even if you have no coupon $1 is a pretty good deal for this brand!
