Any such module for this?

Hi,

I am trying to re-build a website and keep this existing idea for how the products are connected.

Live website: http://www.rlpetproducts.co.uk/store/ca ... s/applaws/

On the existing website, there is 1 main product (which is non purchasable) and then all the actual purchasable options of that product such as the 80g tin, 90g tin, 100g tin etc.

SEE ATTACHMENT OR LINK ABOVE.

With opencart, there is the 'options' functionality the the 'price' field on this is simply a - or + of the main price, instead I need each option to have its own price as shown in the existing website.

Option 2 - if possible
I could import all related products as unique individual products, related them to the main product and then just list them on the product page under the 'related' products. However for example the 5 related products will show up in the search results, so instead of seeing "Cat Tuna" and then 5 related products of "Cat Tuna" when clicked in, the category pages would show all 6 products (which is what I don't want). There would be 6 copies of the same image for instance.
