Got a WordPress based eCommerce [url removed, login to view] to do two points in the delivery section.
[url removed, login to view] to create calculate the delivery price according to the postcode...
for The first 10 miles the delivery is free and every mile after is $5 dollars,that cost need to added to the total cost
hope this can be done by calculating the distance between the store location and customer delivery address postcode
2. In the check out if the delivery is selected ...need to ask another question like a radio button ...
" Need extras ? Yes / No ."
if the client select 'yes' another $20 added to the total
Let me know how long you need to do this and your best price
