[TYPO3-shop] shipping 0.00 for products stored in a special storage folder

[Daniel Ciunkiewicz]

Dear All,
 
I've a tt_products running on one of sites made by me. At the beginning
there shall be only books with a shipping cost of 3.20 EUR (no matter how
many books are in the basket). I've declared something like this:
plugin.tt_products.shipping.10.price = 3.20 and it works fine, but the
customer needs to sell e-books too and there is no sense to add shipping
price for a digital product.
Please let me know if there is any possibility to declare special shipping
price of 0.00 EUR for products stored in one storage folder (or maybe of one
category) and how I could handle something like this:
- till there are only products like e-books in the basket, there should be
no costs for shipping
- if there is not only an e-book but normal book in the basket too, the
shipping cost should ne 3.20 EUR.
 
Thanks in advance for Your help.
 
Best Regards
Daniel
