The estimated delivery time is based on 3 day handling time of the shipping service selected, and when the seller receives cleared payment. 
The estimated delivery time in your order is given by USPS and they are not always accurate .
FIRST CLASS/STANDARD USUALLY TAKES 3-6 BUSINESS DAYS BUT IS NOTGUARANTEED.
PRIORITY MAIL USUALLY TAKES 2-3 BUSINESS DAYS BUT IS NOT GUARANTEED.
We are not responsible for transit/delivery times-. The transit/delivery time listed under the shipping info tab is an estimate, and NOT a guarantee, so please place your order in advance.
I strive to offer a fast mail service, however I have no control over the USPS transit time and CAN’T GUARANTEE the date you will receive your order.
