Can delivery cost be a negative value(give discount), and can a product be locked to a certain carrier?

[cecepee]

Is it possible to add a delivery choice that has a negative value? For example, i order some books, and i can choose from expressmail 10$, snailmail 5$, or pick-up at warehouse -3$ that means if customer choose pick up at warehouse he will get a 3$ discount. Is it possible to do something like this?

Another question is if its possible to lock certain products to only one type of delivery? for example if you buy books and shoes you can chose any delivery you want, but if you buy clothes you can only choose snailmail. Is it possible to do something like that?

Thank you.
Best regards

Seems that no one knows or that its not doable.

So let me do a new rephrase of the question,
I want that certain products shall go with certain carriers, can i do that, force a product to a certain carrier?

Thanks again
Peter

Hi Peter,

Regarding the -/-3,00 discount on pick up, I have the same question as you have, hope you have found a solution in the meantime?
Iam trying to configure vouchers for it, but this solution is far from ideal.

thank you
kind regards

Hello Marianne

No, i am sorry, but i have not found any solution for this, i also thought about vouchers for it, but its not a good way at all.

So i am still waiting for a better solution to this.

Best regards

Hi guys,

 

I was also looking for a way to place a free shipping (as a discount) on specific products and, as I found a solution, I thought I'd share with whoever needs it.

 

Changing the additional shipping costs seemed to be the easiest way to do it, but as you also noticed it didn't work. I tried updating the field (additional_shipping_cost) directly in the database and this was possible and it also seemed to work fine.

 

After looking a bit in the code, I managed to find out how to avoid the field from being validated.

 

In the directory classes, open up Products.php , go to line 214 (in my 1.4.5) and change

'additional_shipping_cost' => 'isPrice',
to
/*'additional_shipping_cost' => 'isPrice',*/

 

The field will no longer be validated, so you can enter any value you wish. If it's a negative value, shipping costs will be deducted by this value. If you write in the exact shipping costs, they will be displayed as 0. Just make sure you use the right amount(in my case I had write in the VAT free amount).

 

I have not tested it completely nor tried to do it on a different Presta version. Please make sure you create back-ups of your files and do this at your own risks. I will come back with infos if I find any issues with it.

 

Hope it helps

But the problem is if you will do it this way and someone adds the product twice the negative cost will be deducted twice..

Yes, you are right! Additionally to that, adding a "free shipping" product + a non free shipping product would also reduce the total shipping costs.

 

This solution, besides the fact that its not suitable for all situations, should only be applied for special products, not for an entire website. Managing these costs can be quite an issue too.

Still looking for a solution? I am !

 

I'm thing of a carrier with lower price (and place a comment in it's name: "use ONLY for 1 item per order, mailbox delivery)

and write a notification for the client to choose the right shipping method.

 

If nobody has a solution.....
