Free Shipping only certain items. All other items perunitweight

Version 1.3.8a

I need two different shipping methods.
(1) if a customer buys 1 of 3 products (only of these three), then they will have free shipping. there is no reason for a customer to buy more than one of these items.

(2) If a customer buys any other items on the website, then shipping is charged according to weight. (peritemweight)

Shipping is simply calculated. It does not use UPS, USPS or anything else.

I have freeoptions turned on. Then I have weight and cost set to 0.

I have freeshipper turned on I have shipping cost set to $79.00, set to taxable goods. no shipping zone.

Then I have perweightunit turned on and set to 1 where it says this...
The shipping cost will be used to determin shipping charges based on: Product Quantity * Units (products_weight) * Cost per Unit - in an order that uses this shipping method.

Here's what I want (in a perfect scenario)

A customer buys a product (with free shipping) and a product (that pays for shipping) Whenthey check out, they see one shipping price say $129.00 - $79.00 (promo free shipping for MT250), then the final price of $50.00.

If this is not possible, then only show a shipping price of $50.00

However, what I'm seeing now is two options for shipping

(1) Free Shipping $0.00
(2) Best Way $50.00

Of course, no one is going to check on "Best Way" since Free Shipping is offered above.

Is what I'm asking possible?

Thank you SO MUCH for your help.

You could try putting the 3 special products with the free shipping in a different product type.... rather than having them in the general product type, like your standard items, list them in the Free Shipping product type section..

Quite honestly, I'm afraid to change categories. There is so much customization that I can't move anything without fear of losing everything.

Any other suggestion?

I've had a little more time to think about the answer. I found the place where you want me to change it to free shipping - products, but it doesn't seem to do anything.

Also, there's another element that was not addressed.

When you check out, it will say the amount of the "discount" given for the free shipping"

Basically, it's a $79.00 discount on shipping when you order one of the three products. you still pay shipping on other products that you buy.

Maybe I put too many criteria in one post. Any suggestions on how to break it down?
