I would give no stars if possible. DO NOT recommend them for how they treat their sellers. I posted several Coach purses that I had bought at a Coach store a few years ago. I followed all of their rules and recommendations. Because another user saw my bags and questioned the Coach product tag, with the words 'Handcrafted in China', my listing was removed and I was marked as a monitored seller for offering 'fake' merchandise.
After looking at many other purses, bags, etc. from Coach on their site, I found that all of the listings had a similar label. I further researched and found that Coach has been making their handbags in China since 2002, and there are quotes from one of the CEO's about the efforts Coach has made to ensure quality out of China.
Poshmark should have known this. But instead they took the word of a Poshmark user. I sent an email to challenge the fraud claim, but after no response, I deleted my account. 2 days later, I get an email indicating they can't find my account. I responded, and again nothing. So long Poshmark, sometimes you just have to stick with the original selling website - Ebay.
