Olay Regenerist Cleanser + Publix Scenario

Publix normally sells Olay Regenerist Regenerating Cream Cleanser for $6.99. This week as advertised it is apart of the $2.50 off sale making it $4.49/1. This is a very sweet deal to start out with... but wait, it gets even sweeter!

I bought two of these when I did my weekly shopping trip on Wednesday. I am well stocked up on this product from previous sales so I've decided to add it to my donation bin where I am hoping to accumulate several hundred dollars of merchandise before actually donating -- my husband would like to write it off on our taxes next year and doesn't want me to do the donating small amounts of the time. And I agree, if we're going to donate we're going to donate A LOT of stuff all at once rather than make several small trips (way not to waste gas, honey!)
