You’ve probably seen the ads on Facebook – “Get $40 worth of sushi for $20.” Though these ads may seem too good to be true, they’re not.  Groupon is just one of several voucher companies that negotiate huge discounts—usually 50-90% off—with popular businesses.  Customers get great deals, and businesses get new customers.  It’s a win-win situation.  I’ve bought several vouchers from different companies, such as Living Social, Groupon, and Home Run. They’re a great way to try a new business in your area for half price.

Here are some of the Bay Area deals offered today (act fast, because many of these deals only last 24 hours):
