We offer 2 type of delivery to uk customers
spend over £100 and get it free special delivery
spend under £100 and get it free 1st class record but option of Special Delivery for extra £3.
Cannot work out how to enable to in Magento (1.7.0.2)
So how can I add the free with £3 option for carts less than £100?
So I found this extension: http://www.webshopapps.com/uk/free/matrixrate-shipping-extension.html
This is the table I used:
"Country","Region/State","City","Zip/Postal Code From","Zip/Postal Code To","Order Subtotal From","Order Subtotal To","Shipping Price","Delivery Type" "GBR","","","","","0","99.99","0","Free 1st Class Recorded" "GBR","","","","","0","99.99","3","Upgrade to Special Delivery Next Day before 1pm" "GBR","","","","","100","9999","0","Free Special Delivery Next Day before 1pm"
Which works like a charm - hope this helps
