Plastic Bins and containers:
Good buys: Walmart but only the expensive ones. $5/ea
No Good: dollarama or dollartree (they break in 2 months)

Crafts:
Here's a comparison of prices (at time of this post):

Dollarama Walmart Online
Pompom 80 / $1.25 30 / $1 0.5 Kg/$6.99 (www.dealsorigin.net)
Chenile Stems 40/$1.25 48/$1 100/ $1.7 (www.dealsorigin.net)
(pipe cleaners)

I also buy online Glue sticks (box of 24 for $5.99), glitter glue and other stuff. The trick is: buy min order to get free shipping.


One thing in common: They will all go to garbage at the end of the day at any daycare
