Etsy Finds is a daily e-mail that Etsy sends out to subscribers. If you have not read my first post on Etsy Finds I would suggest that you start here.
Every Friday Etsy includes weekend deals in their etsy finds e-mail. To be considered all you need to do is post a response in the corresponding forum thread. For the weekend of 06/26 - 06/28 they are looking for Summer Jewelry deals. If you have a summer jewlery deal I would post your information in this thread: Summer Jewelry Weekend Deals. This is a great opportunity to have a chance to reach a large number of people.
If you do decide to post keep the following guideline in mind:
"Please present the instructions for your promotion in a clear way that is easily understandable to first time shoppers."
