The site launched with inventory from over 25 boutiques, from Los Angeles, Miami, New York and Chicago. The site finds these local boutiques by partnering with magazines like Elle to find interesting stores and also receives many leads via word of mouth recommendations. Currently, boutiques are organized by location, and neighborhood on the site, and the price point on items ranges from $50 to $300. You can also shop by category (bags, shoes, tops etc.).
If a customer chooses to purchase an item on the site, Shoptiques will immediately send the boutique an email with the order and a printable FedEx label with the customer’s address. Shoptiques handles all of the payment processing and takes an undisclosed fee from each transaction.
Eventually, Shoptiques wants to expand internationally and add many more boutiques. Although I wouldn't use this website, I did find the concept quite innovative and appealing to a certain segment of shoppers.
