We originally ran the post for the free trip sweepstakes through Herdez last week. This is a reminder. You can still enter the sweepstakes for a limited period of time. Win a trip to Mexico this Cinco De Mayo holiday and visit the place where this holiday originated! Test out your Cinco De Mayo knowledge and be automatically entered in the Herdez Cinco De Mayo Sweepstakes. But, you should enter soon. This free trip sweepstakes ends May 17th, 2015. Daily cap of 700 signups per day.
