The only expiration date was for the purchased item. There however was no expiration date on the credit that was being promoted (e.g. Spend $95 and get $95 worth of Warby Parker plus $25 credit on Gilt). So I went ahead and spent the Warby Parker amount within the explicit timeframe and saved the Gilt credit for a time I actually wanted something from Gilt. Any good company, like LLBean, JetBlue, or SouthWest don't have credit expiration dates, and if they did would be transparent and explicit about them. Customer service was unhelpful and said the credit expired shortly after the Warby Parker amount expired. I had hopes for Gilt and am surely disappointed. You can count on me going to Groupon, Nordstrom Racks, and TJMaxx for discounted quality products and services in the future and leaving Gilt in the dust.
