With the $10.00 discount voucher for Dstore's birthday, you can get an 8 pack of Crayola twistable metallic crayons for $1.90 delivered. (Usually $11.90 delivered).
I did what Admin would do and try to find something for free, this was the 2nd closest I got.
Don't forget your couple of cents cashback!!
Some other good news: According to Dstore, you have to be 3 years old to use these, but with the others you had to be 4!
