CafePress $5/month premium shop is honestly the best way to go. Starting a website from scratch, and getting traffic can be a time and money intensive process, let alone the process of ordering and managing inventory...and it can take months or years for your site to get any free traffic at all.If you want a unique domain, you can register one and have it forwarded to your cafepress site. So if you tell someone to go to BobsTShirts.com it ll send them to cafepress.com/bobstshirts .
