Help! Where can I find the Wrinkle Free Spray???

It is supposed to rain Saturday for my wedding and I know my dress will get really wrinkled. I was told to buy a spray called Wrinkle Free. I cannot find it anywhere.
Supposedly they sell it at travel shops and The Container Store - none of which are nearby. Only have a day left and was hoping someone might know where on LI I can find it?




I have tried Duane Reade and CVS. No luck so far

DOWNY WRINKLY RELEASE!! OMG this stuff is amazing.. smells great and works fantastic.. i hate ironing i use the stuff almost every day.. test a small spot for the dress tho.. just in case.. but you can find it down the laundry aisle in most grocery stores..
