Another question that I see asked time after time is;
How do set up osCommerce so that any order over £50 has free shipping?
The easiest way is to go into your admin area > modules > order_total
Now click on the shipping module, and press . This brings up a screen like this:
The bit that we are particularly interested in is this:
Simply insert a number in that box! If you want free shipping over £50, insert 50. Free shipping over £75, insert 75. And so on. Once done, press [update].
Note that this order_total module setting OVER-RIDES any charge that is applied via a shipping module.
Isn’t that easy?
