Limitations? Have you ever developed your own shopping cart to sell something online and sign on up with a 3rd party processor who not only takes a % of every sale but also charges you $x per month, and sign up for SSL? With bitcoin you can set up your own webstore in a few hours, no 3rd party payment processors fees, no SSL, more money for the merchant, better prices for the people. But you're not for the people, are you?
You can set up a "web store" to take Doge just as easily. While you're at it, don't bother with SSL or even buying a domain name.
Set it up on TOR, as a hidden service, you'll have just about as much business
