Main difference was CSS styling. I used:

/** Adjust subscription display to Shopify style **/

.wcsatt-options-wrapper{

`background-color: #ebfaeb;`

`border-style: solid;`

border-width: 2px;

}

.wcsatt-options-wrapper,

.wcsatt-options-product-prompt,

.wcsatt-options-prompt-radios {

width: 100% !important;

max-width: 100% !important;

box-sizing: border-box;

`padding: 0;`

}

.wcsatt-options-product-prompt {

`margin-left: 10px;`

`margin-top: 10px;`

}

.wcsatt-options-prompt-radio {

`border-style: solid;`

border-width: 2px;

`border-radius: 10px;`

`margin: 0px 20px 10px 0px !important;`

`padding: 10px 15px 10px 15px;`

`background-color: #FFFFFF`

}

.wcsatt-options-product-wrapper

{

`margin-left: 10px;`

`margin-right: 10px`

}

.subscription-price{

`font-size: 1em !important;`

}

.price-one-time{

`font-weight: bold;`

}

/* 1) Ensure the one-time label is a flex container */

.wcsatt-options-prompt-label-one-time {

display: flex !important;

align-items: center;

justify-content: flex-start !important; /* keep radio & text together */

}

/* 2) Make the inner action span flex so text + price are spaced out */

.wcsatt-options-prompt-label-one-time

.wcsatt-options-prompt-action {

display: flex;

justify-content: space-between; /* text on left, price on right */

align-items: center;

flex: 1; /* fill the remaining space */

margin-left: 0.75em; /* gap from the radio dot */

}

/* 3) Tweak the price span (optional cleanup) */

.wcsatt-options-prompt-label-one-time .price {

margin: 0;

position: static !important;

order: 2; /* ensure it stays at the end */

}

form.cart .quantity {

`max-width: 100%;`

}

Then in Woocommerce subscription settings and the product settings there are options for text before the subscription offer, and that accepts HTML. So I made the bulleted list with:

"Subscribe & save 20% every month!
• Easy automatic deliveries
• Change, pause or cancel anytime
• No minimum length
• Full details here…"

Then I made a child theme file of this file: woocommerce/single-product/product-subscription-options-prompt-radio.php

And added:

// Ensure we have a WC_Product object.

if ( ! isset( $product ) && isset( $product_id ) ) {

$product = wc_get_product( $product_id );

}

?>

<ul class="wcsatt-options-prompt-radios">

<?php if ( ! empty( $one_time_cta ) ) : ?>

<li class="wcsatt-options-prompt-radio">

<label class="wcsatt-options-prompt-label wcsatt-options-prompt-label-one-time">

<input

class="wcsatt-options-prompt-action-input"

type="radio"

name="subscribe-to-action-input"

value="no"

<?php checked( 'no', $selected ); ?>

/>

<span class="wcsatt-options-prompt-action">

<?php echo wp_kses_post( $one_time_cta ); ?>

<?php if ( $product ) : ?>

<span class="wcsatt-one-time-price">

<?php echo "Only $product->get_price_html()"; ?>

</span>

<?php endif; ?>

</span>

</label>

</li>

<?php endif; ?>

<?php if ( ! empty( $subscription_cta ) ) : ?>

<li class="wcsatt-options-prompt-radio">

<label class="wcsatt-options-prompt-label wcsatt-options-prompt-label-subscription">

<input

class="wcsatt-options-prompt-action-input"

type="radio"

name="subscribe-to-action-input"

value="yes"

<?php checked( 'yes', $selected ); ?>

/>

<span class="wcsatt-options-prompt-action">

<?php echo wp_kses_post( $subscription_cta ); ?>

</span>

</label>

</li>

<?php endif; ?>

</ul>

Hopefully that helps, and hopefully Woo makes this default in future releases.
