VM2: how to add fixed costs to product shopping cart page

[sfigattomambo]

Hi to all,
I'm trying to add some fixed costs to my VM2 product shopping cart page.
I have products that depending on manufacturers or materials could have some fixed costs, these costs must be added ONLY to the final price.

Example:
I want to buy 100 cotton shirts and the cost of each shirt is 1 (one) dollar. My final cost is 100 x 1 dollar = 100 dollars
At this final cost I have to add 30 dollars as "start of work" cost, a cost to apply to final cost and not to each single shirt.

I could I do this in VM2?

Thanks & regards
Giovanni

hello sfigattomambo,
Not sure if I can help, but trying to get a little more information.

Is the $30 constant, meaning $30 for 100 shirts, but what about 10 shirts, still $30?

I've been looking into custom fields and cart variants, might be a way, not sure right now.

Hi mowlman,
many thanks for your reply.
I have two different type of costs:
- the first one related to quantity
--> from 1 to 100 shirts: 0.50$ additional cost for each shirt
--> from 101 to 200 shirts: 0.40$ additional cost for each shirt
--> from 201 to 300 shirts: 0.30$ additional cost for each shirt
--> and so on

- the second one is a fixed cost (for example: 30$ even if the shirts are 100 or 10)

Do you have any suggestion?
I created some custom fields as cart variant but I can't create exactly what I want.

Thanks & regards

For a final fixed charge use a Tax/Calculation rule set to Price modifier before tax per bill, maths operation + with the value as the surcharge to be applied. This can be applied to single or multiple categories and/or manufacturer as required. Use multiple instances if required. The ectra charge will only be shown in the cart at checkout.

Hi jenkinhill,
many thanks for your reply.
I added a new rule to the final bill amount and all goes well.
