I've been building an ecommerce site to offer merch and promote @spiral's HereComesBitcoin ~design stickers. Not sure if there's a real need, but for now I'm enjoining the challenge to manage such big database of products (over 100 designs and planning to offer at least 4 products for each design). Has anyone built something similar? What would be the best advice market or promote it? What would be the best merch to offer?
