A reader writes in to warn that if you purchase from Cascade Toboggan, be prepared to be treated with suspicion and hostility, and to have your order canceled if you attempt to straighten things out. Michal used a fairly common spam-tracking technique when he placed an order with them earlier this month—he put their company name as part of his email and shipping addresses, so that if his information was sold, he’d be able to source the perpetrator. We’ve done this ourselves in the past, and it works. However, the owner of Cascade, Dana, says this is trademark infringement, and even after getting Michal to agree to remove the name from his personal info, canceled the order and effectively banned Michal from future business.
