My store has extra long flexi pencils for .17 on the clearance shelf (in mine, it's on an endcap)
They also have regular sized m&m bags (like vending machine size) for 2/1.00.
The have walgreens soap 4.5 oz 39 cent each
I saw Big Bite mints on sale yesterday for .25 in the easter section. They are in a blue tin with a shark on the front and a "bite" taken out of the tin.
I look at the seven day fillers too. This week I bought .79 kleenex boxes (I'm in the middle of a major cold). I'd rather spend a few cents more for stuff I'll use instead of ending up with even more pencils and candy ;)
also this week they have the yellow mailer envelopes 3/$1. that's a good deal.
Ramen noodles (always regularly priced at $0.29 each or 4/$1).
