We use facebook for our giveaways. Its fun! We have them like our page and a message on our wall. We trade likes for admissions. For example we did a shirt giveaway a couple of months ago and we had the contestants write the name of the shirt on our wall. It is our Seas the day shirt: https://www.etsy.com/listing/83314096/fishing-scuba-surfing-gift-seas-the-day so to enter they had to write seas the day on our. We got decent amount of participation from it and now we can market to more people who like our stuff.
