A/B test: show a delivery date instead of a delivery range
If the shipping step says “Arrives Thursday 12th” rather than “2 to 3 working days”, then orders will rise, because a specific date is understood at a glance and a range has to be worked out.

Why it can work
“2 to 3 working days” means doing sums. Does today count? Is Saturday a working day? Will it arrive before Friday's birthday? Lots of people skip the sum and keep the doubt, which is the worst thing to carry into the payment step.
“Arrives Thursday 12th” answers all of that at once. If the order is a gift or something needed for a specific day, it is exactly the information that decides.
How to set it up
Check your platform first. Many of them restrict what can be changed inside the checkout, and Shopify is the strictest: there you may only be able to run this test in the cart or on what shoppers see before paying. On WooCommerce or PrestaShop the checkout is just another page of your site and can be tested like any other.
In Bixlow you describe the change to the agent, it builds it on your site and launches it as an A/B test once you approve it. A/B tests are on the paid plans, starting with Standard.
- Work out the date from your real cut-off time: if orders before 2 pm ship today, the date changes at 2 pm.
- Account for weekends and public holidays. A date you miss is worse than a range.
- In the variant, each shipping option names the day: “Standard: arrives Thursday 12th”, “Express: arrives tomorrow, Wednesday 11th”.
- If your checkout can't be changed, put the same date in the cart, just above the checkout button.
