Lays Stax are on sale for $1 and are printing a $1 +Up Reward making them free! They are also part of the "Spend $15 on this page and get a $5 +Up" which includes products from Planters, Oberto and more.
Afrin is also producing a $4 +Up reward. So you can buy 1 @ $5.99, use the $2/1 found here or the $3/1 in the 1/2 Smart Source if you got it. (mine didn't have one)
Afrin counts toward the Buy and Save too!
