No, these aren't coupons you use somewhere else. Zulily sells the goods and focuses on stuff for kids and mothers. Also, they seem to pick quality stuff, not just anyone trying offload crap like some other flash sites. My wife uses Zulily all the time and really likes it.

Hopefully this IPO will enable them to ship stuff quicker though, that's the only major complaint about Zulily from everyone I know who uses it.
