Quantity Discounts for shipping 1.5

Hi,
I looked around for an answer but couldn't find anything. I am using 1.5.0. Here is my question...
I am selling products that all have the same shipping price of $7.99 but if someone orders more items shipping to the same address I want to charge only $2.99 for each additional item. How can I go about doing this?

If it can be done but requires special coding, please send me a private message with an idea for a cost. You can also include your name and number (if in the US) and I can call you for specifics.

You can do this sort of thing with Table Rate shipping.

... with one small change: where it's computing the price for non percentage prices, multiply by $order_total less 1.

} else {
$shipping = $table_cost[$i+1] * ($order_total - 1);

This is line 122 in 1.3.9, 1.5.0 and 1.5.1.

This is probably obvious, but you would also set the Table Method to item and the Handling Fee to $7.99, and the Shipping Table to
100000:2.99

What file do I edit please? I am a novice at this lol

includes/modules/shipping/table.php

thank you sir!

so do replace line #139...

$show_box_weight = ' (' . number_format($shipping_weight * $shipping_num_boxes,2) . TEXT_SHIPPING_WEIGHT . ')';

with the new code or do I add the new code below it?

Another way to do this without changing any code, is to use the Per Item item shipping module ...

Set the Rate per item to: 2.99
Set the Handling to: 5.00

Now you get the charge of:
Qty 1 as 1 x 2.99 + 5.00 = $7.99
Qty 2 as 2 x 2.99 + 5.00 = $10.98
