flat rate shipping based on weight?

Hi,

Is it possible to do a flat rate shipping based on weight?
I need to add a 'registered mail' option to my shipping modules.
and this registered mail service charge the customer by weight.

For example:

I want to charge $2/2kg. which means the system will automatically adds up the charges based on weight.. like this:

$2/0-2kg
$4/2-4kg
$6/4-6kg


Pls help. if this method is possible. Thanks!!

Well, this is not strictly a "flat rate". if you have different prices for different weights, then it can't be a "flat" rate.

Flat rate means only ONE price will be charged for shipping a consignment, no matter WHAT the weight or distance is.

You will need to configure one of the TABLE or ZONE modules to input the variables you have described.

If you need "duplicated" shipping systems (one standard rates, one registered rates), then the way to do this is to create a CLONE of a module (so you replicate its functionality) and you configure the cloned module to handle the rates for the alternative option.

There are posts on the forum showing how to clone a shipping module.

The post by Fairestcape in this thread is a good place to start.

Do you mean i can configure my table setting to work together with my registered mail function?

I don't quite understand how the table works, but right now i have successfully clone two more flat rates modules. one- 'normal mail' and the other one - 'registered mail'

I only need the table rates to apply to the 'registered mail' .
and to make this function shows up on whenever there's orders, and ignoring my free shipping settings, as the free shipping options only applies to 'normal mail'

How do i do this??

Hi Schoolboy,

Thanks for your advice!
I managed figured out and change my 'table rates' to 'registered mail' so it works by weight calculation!

But have done a setting to offer free shipping for orders over $69, and whenever order hits above $69.My registered mail option is gone too .

How can i make it stay as a permanent option during checkout?

thanks and hope you could help me on this.
