Selecting "First Class" postage from Radio buttons is causing two postage charges to be applied?
On our checkout page, once you have entered your billing and delivery address, we have an option that allows you to select your preferred type of postage via three Radio buttons:
First Class Delivery
Next Day Delivery
If you select "First Class" Delivery and click "Continue" and then scroll back up to review the order there are two lots of postage added - in effect two different postage rules!
I attach checkout.php as I can't work out why eCart is applying two postage rules. Hope you can help. Thank you.
