Serengeti is owned by Potpourri group. If you ever ordered from any of their divisions and you visit another of their websites, they send unsolicited emails to the email address they have on file for your order.
I ordered from Serengeti, and then when I got a catalog in the mail for North Style and checked the website, I had 8 emails within a few days. Which indicates that they're tracking you by IP address, which they've matched to your email address.
I got off the mailing list, but I resolved never to look at any of their websites again. You can see their companies at https://www.bbb.org/boston/business-reviews/mail-order-and-catalog-shopping/potpourri-group-inc-in-n-billerica-ma-21005.
Reason of review: Poor customer service.
