Well, they seem to be in violation of the FTC's Mail Order Rule.
First, who are they? Their street address is
2409 20TH ST
BOULDER CO 80304
US
which is a house.
A Colorado corporation search gives a second address:
1738 Pearl St., Suite 2A, Boulder, CO 80302, United States
which looks like office space above a restaurant in Google Street View. Their landlord is Pearl Street Properties (http://www.pearlstreetmallproperties.com) and calling them during working hours might be helpful.
They're incorporated in Delaware, but are delinquent in filing with Colorado. Delaware corporation search only works on weekdays, so not much is available from there tonight.
The founder is Alicia DiRago. Not only is the company not communicating, her rather busy personal online life has stopped.
Here's her Twitter feed, which stopped on September 3, 2014: https://twitter.com/aliciadirago
Here's her other startup, Dismount Creative, which was last updated on August 3, 2014: http://www.dismountcreative.com/
Her personal Facebook account, last updated in January 2014: https://www.facebook.com/alicia.dirago
Definitely the right person; she's wearing a Whimseybox T-shirt in her profile picture.
She's married and lives in Boulder, CO. The address is a matter of public record, but I won't list it here. Her husband, Joseph DiRago, is an attorney in Boulder. No news items or obituaries for either of them.
This is a very tiny operation and there's probably a personal problem. This isn't a big enough business to be a scam.
