Many people have reported finding Vivactiv clearanced at Walgreens to around $3.49. There is a coupon in the March EasySaver catalog for $2 off. There is also a 7-day coupon in this week's flier for $3 off, as well as manufacturer's coupon in the 3/2 paper insert for $3 off. You could potentially make more than $4 each. This would be a great deal to combine with this week's soap deals.
And for some free Visine, check your Walgreens for some clearanced to $2.99. Use the $3 manufacturer's coupon from the 3/2 paper (this coupon will probably need to be adjusted down to 2.99).
Edit: The Visine isn't clearanced--it's on sale this week for 2.99. So your store should certainly have some. :-)
