Most orders ship within 1-2 days!
We are closed on Memorial Day, July 4th, Labor Day, Thanksgiving Day and the Friday after Thanksgiving. At the close of each year, we are closed for Christmas Eve and the following week, reopening the first business day after New Year's Day.
During the months from February through May our lines are very busy and despite our best efforts, there may be times when you are not able to reach us by phone unless you leave a message. Please let us know the reason for your call so that we can have the correct person call you back! We will return your phone call, usually within a few hours, and almost always the same day.

You may send us an e-mail using the form at the bottom of this page. We reply to your message as quickly as possible, usually within a few hours during the business day. This is often a faster way to reach us than phone during the spring months. If you are emailing to request a change or cancellation, it must be done within 2 business hours after the order is placed, and we will respond by email. Do not assume that we have received your message unless you get an email confirmation from us.
