A search of the business name reveals this:
Also, the address on the website is 1800 S Powerline Rd, Unit F, Deerfield Beach, FL and the address of 1800 S Powerline Rd, Unit E, Deerfield Beach, FL (which would be right next door) is a business called "1st Class Cigar Humidors" which also has the same type of complaints against. them.

I came across this web site when looking for chess boards for my grandsons. Most of the boards on this site are nice-looking and rather inexpensive, but I can't find any reviews for the company. I called them with a couple of questions and got an answering machine; left a message, but no callback. I would be interested in whether you have had any dealings with this outfit, good or bad. Thanks.
