Here's the info from their site, or follow the link above to their event listing:
Please don't forget that this coming Saturday, November 12th, is our annual "TURN FOR TROOPS" event and you are welcome to come to the store between 10 am - 5 pm and turn a pen for free - and the pen and your note of support will be sent to our troops overseas! This is a terrific way to thank them for their courage and let them know they are thought of by those in the homeland. (Even if you have never turned before...it will only take about 20 minutes of your time, thanks to our team of dedicated volunteers!) Your partticipation will be valued and appreciated, and we'll look forward to seeing you!
