Daily Deal sites continue to come on the scene as Groupon valuation surges past the $1 billion mark.

Some competitors coming on the scene include:

HomeRun.com – A little bit about HomeRun.com

In October 2009 all our friends were working hard. The whole country was in a bad recession. The economy was tough. So we decided that a lot of people would appreciate a fun website that makes it easier to enjoy great things nearby. Every day we provide one amazing offer to our members. You have to sign up on the website to get our deals, or sign up to receive our daily email — either way, membership is completely free to you. Some days we surprise you with something new. Some days we remind you of (and help you return to) things you love… Each daily deal is an offer for something great that you haven’t had the time (or money) to do in the last couple years.

We started HomeRun to be an exciting, fun website. More fun than Ebay. Simpler than Priceline. Easier than Amazon. Yes, we offer daily deals at unbeatable prices through the power of group buying. This has always been a good idea – people have tried to make this work online since 1999. And we felt the time was right, now.

We set out to make a place that our friends would love, and use. And share. We treat our customers like our friends, because we all want amazing experiences in life. So from the moment you buy your HomeRun to the day you use it, we want each offer to satisfy you completely. We strive hard to knock it out of the park.
