I saw these 10 count Sensi strips at Walgreens on clearance for $3.49 each! Original price on these were 28.99 and they were reduced several times as I could tell by the tags. I don’t know why they are so cheap, but I think they may be trying to phase out the 10 count packages because if you search for the Sensi strips online, they only show the 6 and 12 count. Anyways I use the $3/1 P&G 9/27 coupons getting them for only 49¢ each!!! If you find the 10 ct at your store and they aren’t marked ask for a price check, you may be surprised!!
