I have purchased many things from zulily since 2011. Known brand items have always been winners, but several impulse buys have been lower quality than expected. On the few occasions that the wrong item was shipped or the correct item arrived in poor condition, ZULILY OFFERED A FULL REFUND and STORE CREDIT. Customer service representatives respond to emails within hours and give clear, courteous, personal responses to your inquiries. For most items delivery is Stagecoach slow. Ready-to-ship items arrive within several days. The website and app both update tracking and shipping status frequently during the 1-2 week delivery window. I will say that over the years it seems like there are fewer flash sales of high quality brands. A small but irritating flaw with Zulily is its poor item descriptions; every item "boasts" a generic attribute, but rarely are detailed product specifications or technical details listed. An arsenal of additional verbs for their creative team and product information straight from The manufacturer would be two simple improvements. Small but significant positive features include how easy it is to save an item for later or favorite an item you are not ready to buy (single touch, does not require navigating back and forth between any pages), notification when an item from a previous sale is available again, and better-than-average recommended products (a feature that has gotten even better with recent improvements to the app). Although price and convenience comparisons on Amazon or other sites are worth the effort, Zulily does have great finds at great prices.
