Edit wording at checkout

Site URL: https://www.letrou.ca

Hi, 

I try to find a way to make my pickup options less confusing since Squarespace does not have a "real" option for that at this point.

My clients need to fill their address before to see that there is a pickup option and it is quite confusing for them. Many of them give up.
I would like to change the wording "delivery" by "delivery/pickup" at least at checkout.

I tried to use CSS with something like this :

CheckoutSection-content-1c3bA{
content:"test";
  }

I certainly miss something... if anyone could help, it would be very appreciated :)

(You can't add code to Checkout page /checkout)

I've had the same problem.

It would seem like an easy fix to be able to display (in our case) the option for delivery, pick-up, or mail appear first when checking out and then have the address info etc show up. 

Honestly, I'm regretting choosing squarespace over shopify. Love the way my site looks, but the checkout process is super clunky if you have are giving your customer more than one option.
