I'm trying to place an order on the Playmobil US site, using the coupon the newsletter sent out this weekend, & which is posted on the US website. Even though I've used copy & paste to capture the number from the site itself, I keep getting "coupon invalid" every time I try to place the order. Has anyone else had problems? This is the last day of the sale, & I haven't any minutes on my phone to call NJ to get help.
