does anyone have the code for a single-page checkout of an order they would be willing to share?

I don't, but after struggling with mine, I'd ask why you feel like you want a one-page checkout. Solidus needs to step through different parts of checkout to generate things along the way. Some of the things that have caused me headaches: • can't generate shipping rates until it knows where it's going to send the packages • changing the address means that shipping rates are invalid and need to get regenerated • solidus is set up so that it doesn't ask for payment info until it knows what things cost, so any changes (updating cart qty, changing shipping method) will need you to enter payment info again you might be able to come up with some wizardry that can handle some of that with ajax and live-updating, but that's going to be very specific to your individual setup and isn't likely that we'll have a drop-in solution for it My approach (to try to make it work as closely to the "standard" checkout as I could) was to use the cart page as the "one page", and then include the partials from all the other steps. I use the current checkout step (that solidus already tracks) to disable any steps after where I am to make sure that things aren't entered out of order.

Thank you for pushing me to use the stock checkout
