How to use:
After installation go to Admin -> Catalog -> Edit Product, you'll see a list of checkbox for the shipping methods, check off all the boxes that you would like to enable.
Notes:
* Checking no boxes in the same as checking all the boxes, all the modules will be enabled for that product.
* The shipping module must also be enabled in the Admin -> Modules -> Shipping area for the module to show up.
*** Make sure you dont setup the products in such a way to eliminate the possibility of them being purchased together:
For example:
If you set "Product A" to allow only the Flat Rate module
And set "Product B" to allow only the Item Rate module, if the customer tries to purchase A and B together they will have no shipping options.

If you also have ship2pay installed, you will find that this mod will work perfectly with it!
However, the mod in catalog/includes/classes/shipping.php clashes with the code in admin/ship2pay.php and will not show. So the simple solution I made was to ignore the mod in shipping.php when viewing ship2pay.php by using this code for the two mods in shipping.php:
//bof added to work with ship2pay on admin side
if (preg_match("/ship2pay/", $PHP_SELF)) {
echo '';
} else {
//eof added to work with ship2pay on admin side
---- MOD HERE -----
} //added to work with ship2pay on admin side
The attachment is the shipping.php on how the mod should look IF you have ship2pay installed as well.
This is just a minor mod. Full credit to original author.
