On 10/23 CVS will hold a 2011 Halloween Party and Customer Event! Get a Free $5 gift pack to any child in costume on October 23, 2011 at all CVS/pharmacy locations, while supplies last. (if you have more than 1 child, each will get their own pack.) I believe this event begins at 9 am and runs until 5 pm, but you may want to confirm with your local store.
The gift pack includes $5 value of candy, toys, trick or treat safety items and $10 in coupons for additional Halloween products! The gift pack also includes a free 5X7 photo, supported by an in-store costume photo shoot.
