I stumbled across a fantastic new local website called CityIntros Deals. They offer discounted vouchers, similar to Spotted Fox or Seize the Deal, and have had some great merchants featured in the past.
For each deal that is purchased through their site, they donate a portion to a specific local charity. Each quarter, they choose a new charity. For the first month, 50% of revenue is donated and for the final 2 months, 10% of revenue is donated. This quarter, their charity of choice is Columbia Basin College Foundation.
They currently have a deal going for a $15 voucher to El Chapala in Kennewick for just $7. Tuesday through Friday, they offer an all-you-can-eat lunch buffet for just $7.99 that will make your voucher stretch even further. For every deal bought, $3 will be donated to the CBC Foundation.
Promotional value expires 11/4/12 and can not be combined with other offers, also can not be used at Chapala Express.
