From the OU website:
Succah Website Owner Flouts Beth Din; Denies Wife a Get.
OU Strongly Recommends Not Buying from Site
The owner of the website described below, www.succah.com (note: with this exact spelling only!), is in violation of Jewish law, in that he has not given his wife a get, a Jewish divorce decree. He has failed to comply with an order issued by the Baltimore Beit Din (Jewish court). Until he gives his wife a get, she is not permitted to remarry under Jewish law.
Sam Rosenbloom has a seruv issued against him by the Baltimore Beit Din. A copy of the seruv can be viewed at http://www.getora.com/seiruvim.htm.
Mr. Rosenbloom owns and operates an on-line succah business at www.succah.com (note: with this exact spelling only!). We strongly recommend that no Jewish person buy from his website, that no synagogue grant him an aliyah or other religious honor or benefit, and that no Jewish family invite Mr. Rosenbloom into their home or otherwise provide him with Yom Tov or Shabbat hospitality.
