I would like to make some changes to the text which appears near the bottom of the checkout page, usually it says something like:
You will make 12 payments of USD 40.00, one each 4 weeks
But I have a few issues with this. One is that my client finds the phrasing to be intimidating and would like to change it. Two is that I'd prefer a form like $40 US to USD 40.00.
Incidental to this, I'd also like to have more control over how this page renders, to add some text explaining the coupon code process, to put all of my checkout buttons on one line (using my theme's responsive grid, if possible) and to apply my theme's button styles to the stripe pay button.
