What's in your wallet? If it's a Capital One card, and you live in one of the largest metros in the US, and you like hoping into cars with strangers, then you may be about to get four free UberPool rides.

This weekend, from March 4th through March 6th, Capital One is offering cardholders four free trips. You can take advantage of the deal by entering the promo code CAPITALONEPOOL into the app. If you've chosen UberPool and selected an eligible Capital One card, you should see the discount.

UberPool rides are those that you split with another person who is heading in the same direction. Quicksilver owners also get 20% back on all Uber rides paid using the card until the end of April.

The deal is only available in Atlanta, Austin, Boston, Chicago, Los Angeles, Miami, New York City, Oakland, Philadelphia, San Francisco, and Washington DC. I'll try to ignore how the thousands of Capital One employees who still work where the company was founded apparently don't get to take part in the fun. Oops, I failed.
