Etsy is a gold mine for unique porch signs- just be aware that inventory changes often, and quality can vary. You can find everything from welcome signs to quirky/ humor porch signs, and, of course, signs for every season. The great thing - and challenge- about shopping for a porch sign on Etsy is how much variety there is. If you’re using your sign outdoors, pay attention to the quality of the materials and whether or not they’re waterproof. And while a store's little sales are not inherently a red flag (especially if they’re new), you can play it safe with a store that has a substantial history of sales.
