Staples ad for 7/3 - 7/9
Looks like the "back to school" sales are starting!  This is a good time to stock up on office supplies too.  Plus, some items are good for craft projects.

Below is just a highlight of what I think are great deals and they are just 50¢ each! Limit of 2 each.

Staples pencil box (plastic)
Staples jumbo paper clips, assorted colors (come in a cute little container) - these would be cute in gift baskets or for stocking stuffers
Staples steel hole punch
Staples magnetic bulldog clips, 3/pack
Staples 5 1/2 x 9 brown clipboard

...and the below are good deals but if you want wait, you might find them cheaper. They are 50¢ each too.

Westcott 12" finger- grip ruler (this might actually be a really good one, will have to check it out at the store)
Avery insertable 5-tab dividers (think these are paper, plastic ones last longer)
Staples dual-dome pencil sharpener

Backpacks are 25 to 50% off.  (I would shop around before buying.)

Edited to add this note:  
The rulers I mentioned above are really neat.  They have a raised bar in the middle which makes it easy to grip.  These would be ideal for crafts.  They are made of plastic and look like the little ones might easily break them.  So keep that in mind.
