This is from my friend Charity:
The other day I needed a package of chocolate chips and was unhappy to find them for $2.99 at Walmart. Yesterday I was in Randalls and they had about 100 packages of Nestle chocolate chips on the 50% off table near customer service. Thinking I was scoring a deal at 50% off of $2.99 I bought 5 packages. Lo and behold they rang up for $.80 each AND a register coupon printed for $2.25 off any (5) packages of Nestle morsels. So I kept doing transactions of 5 and getting another coupon. I came home with 25 packages, and a Google search tells me that they will freeze for 2-3 years!!
