product based shipping instructions?

Is there a guide anywhere for this module?

I have a store with a flat shipping rate of 12gbp and free delivery over 500 which we have configured with the standard software.

What we need to do is to increase the flat rate shipping rate for certain geo zones and also for certain products we need to add even more to the flat rate (large items)

Not sure where to start!

You can hover over the yellow ? bubbles for help with the extension settings, and I'm always available for questions via e-mail (which is included in every extension file) or via my contact form: www.getclearthinking.com/contact

Shipping methods in OpenCart are independent of one another, so different shipping extensions cannot be combined or affect each other -- each shipping method that is enabled will be presented to the customer as its own option during checkout. This means you'll need to recreate your flat rates using the extension, and then add additional rates for your other specific products. For example:

------------------------------------------------------------------------------
RATE #1
Title: Shipping
Sort Order: 1
Multi Rate Calculation: Sum
Products: NOT, (blank list) = all products
Rate Type: Total-Based
Cost Brackets:
- From: 0, To: 499.99, Charge: 12.00
- From: 500, To: 999999, Charge: 0

RATE #2
Title: Shipping
Sort Order: 1
Multi Rate Calculation: Sum
Products: ANY, (specific products)
Rate Type: Item-Based
Cost Brackets:
- From: 0, To: 99999, Charge: 5.00

ETC. FOR OTHER FLAT RATE PRODUCTS
------------------------------------------------------------------------------

Make sure the rates have the same Sort Order so they'll be combined into a single cost.

OK thanks for that I'll take another look and let you know if I get stuck!
