T.I.L. Darling Clothing Boutique let's members, in a flash sale format, pre-order brand new in-season fashion items at up to 60% off retail. LIM College recently conducted a survey that found that among 18-25 year olds, only 20% had heard of Gilt.com, RueLaLa.com, and other flash sales site. Most had never heard of one. T.I.L. Darling plans to target 18-30 year old, college-educated women, and introduce them to the concept of a private membership flash sales site.
