‘Pomana’ is the first theme based on WooCommerce, made for Lotteries, Giveaways, or Raffles. Website sellers will have to sell their products (let’s say a limited number of products) as tickets and then make a public raffle to see who is the winner. WooCommerce is the key to this theme including the unique designs optimized for this business type.
