Where are you located? Domino's has an API apparently: https://github.com/aluttik/pizzapi

I rather like Domino's surprisingly, compared to their pizza in the early 2000's its quite delicious now. I'd say its on par compared to Costco, though still a step below your average local pizza chain.

Back in the day, like way back in the day, some programmers at SGI wrote an X application to order burritos by fax from La Castena when it was on Rengstoff. This might have been the first internet (pre-web) ecommerce application.
