The holidays are here, you need to find some unique gifts for your friends and family, and Sports Authority has left the Sports Castle in Denver vacant - this can only mean one thing.

Pop-up flea market Denver Flea is setting up shop as "Holiday Flea" from December 2-4 at the Sports Castle, 1000 Broadway.

Chug back bottomless holiday beverages at the Friday night kickoff party from 5-9 p.m. and get your holiday shopping done all weekend long with access to 200 vendors scattered throughout the space.

Tickets to the Friday night kickoff party cost $30 and all-day, all-access flea passes for Saturday (10 a.m. to 6 p.m.) or Sunday (10 a.m. to 5 p.m.) cost just $5, a portion of which goes back to Denver Flea's non-profit partner Rocky Mountain Micro Finance Institute.

Boulder-based Adorn (whose open diamond necklace is shown above) is just one vendor that will be at Holiday Flea. Check out their Etsy shop and view the full list of vendors you'll get to shop from at the Sports Castle in early December.
