I with to add to {$product_data.full_description} some additional data like weight and additional description that is not in normal product description.
is greyed out text field, editable only if you checkbox "Redefinition of the product name and description on eBay" so unless you check it and save changes none of weigh parameters would be taken in to account.
basically I need some hook that would add additional data to {$product_data.full_description} for ebay addon.
I do not want to modify description for cs-cart store, but it would be good to modify data that is passed on to ebay from {$product_data.full_description} so it would be description + weight + some additional text.
If you want to add weight to all items, may be it is better to update the eBay script?
