You may have noticed the partner stores category on Exchange. This category displays shops that have been made by Shopify partners. Partners are professional web designers who belong to Shopify's partner program.
What makes these stores different? First, they are typically made by professional designers. These stores also have no sales and have not had a previous owner.
They come set up with everything you need to start selling and have not had a real merchant try their hand and making it a success yet. They've been built to sell to buyers looking for a ready-made shop.
