Check out this informative tidbit for you Target endcap sales shelves scavengers, from local LA blog, Atwater Village Newbie:
"Here's a hint we learned years ago from a Target store manager. It seems to still hold true.
Full prices end in 9. Every time Target discounts, the final digit of the price drops. The lowest the final digit will go is 4. If you see something you want and the price ends in 4, buy it. You won't get it for less."
Anyone else out there know of similar discounting codes at other home retailers?
