Only the internet could have a store that only sells one item per day, with a new item every day:

What is Woot and who's behind it?

Woot.com is an online store and community that focuses on selling cool stuff cheap. It started as an employee-store slash market-testing type of place for an electronics distributor, but it's taken on a life of its own. We anticipate profitability by 2043 – by then we should be retired; someone smarter might take over and jack up the prices. Until then, we're still the lovable scamps we've always been. But don't take our word for it: see what the online community has to say at this Wikipedia article.

I see only one item, do you sell anything else?

No. We sell one item per day until it is sold out or until 11:59pm central time when it is replaced (see next entry for details). However, each item we sell is in stock and typically ships within 2-3 business days.
