I have been ordering from Zulily for years, and was delighted at first, but over the last several months have been completely disappointed. The insane length of shipping, I have always just taken in stride because they state it will take 10-14 business days to ship. Bummer, but, ok, fine, at least I'm aware.
The biggest issues I have are the QUALITY and FIT of items I've received. And the fact that much of what is listed, can be found with a quick search on Amazon (for the same or less money), which believes in it's products enough to allow reviews on the site.
The last dress I purchased from Zulily claimed the retail price was $120, while their price was $39. Once received, I can gaurantee that this garment was NEVER $120 anywhere, and by the way, it fit my size 8 mannequin perfectly (it's a knit, so should have stretch, but I ordered a size 2x/16... Soooo... Not helpful). The quality is just bottom of the barrel. It's so disappointing.
After this last order, I will be cancelling my account and never ordering from them again.
