Costume Craze is running a 30-90% off site wide sale right now. No codes necessary, however if you do spend more than $50 you can use code FREE for free shipping.
I love that they have a $2.99 FLAT RATE for shipping, no matter how small your order, so this sweet Valorie Tabor Smith Winged Angel Costume (Reg $38.99, on sale for $7.79) comes to a grand total of $10.80, including the shipping, leaving you with an awesome savings of 73%.
One other favorite I just had to highlight is this awesome
Napoleon Dynamite costume, Reg $48.95, on sale for $4.89. Even if you order nothing else, the grand total will only be $7.88 with shipping for a savings of 84%.
Currently no end date for this event, but Halloween is coming up and the selection will get picked over quickly, so order soon!
