"On October 1, the Postal Service will implement new service standards for First-Class Mail and Periodicals. These new service standards will increase delivery reliability, consistency, and efficiency for our customers and across our network.
We do our very best to have a no longer than 48 business hours turn around on shipping your order; once we hand off to the carrier you have selected we sadly no longer have control over delays or mishaps with your order. Please contact us if there's a problem and we will do all we can do on our end to help.
