Yes - it pains me because I hate when a good company goes bad. I've worked with Nationwide since 2008 with no problems.
Do a search for Nationwide using all dates. There have been discussions since Fall 2012 of shoppers not being paid. One reported being out a couple of thousand dollars. I am out about $150 total, from two shops, one early October and one December 1st. They have been reported to MSPA, and Dan Denston of MSPA communicated with Nationwide. While Dan was able to get responses from Nationwide to the unpaid shoppers, all the responses said was "We're working on it. Thanks for your patience."
At this point, they appear not to be paying or responding to shopper inquiries. Apparently some shoppers have reported them to BBB, because they now have an "F" rating because they have not responded to the BBB. Their Sassie site is still active, but they currently have no jobs posted in the US. I know they lost a big client (the one I used to shop for them is now shopped by Bare), and that may have started their downward spiral. I should have been suspicious when Laura Unger, their long-time scheduler, left the company last fall to "do something different." I have been told privately that several shoppers have reported the non-payment issues to Nationwide's clients, which probably resulted in Nationwide losing additional clients.
It looks to me as though anyone who has not been paid will not be paid. Sigh. This will be the first time I've been burned.
