Please advice how I should set up my shop

[termenator]

This is the last thing I need to do before my shop goes live.

I am selling cosmetic. I have a product #123 for 10 oz. of shampoo, and #456 for 16 oz. of shampoo, and #789 for 24 oz. of shampoo. How can I set up in the product page that I offer three different sets of product (3 different product numbers), if the customers pay $3 more, they can upgrade the shampoo from 10oz (product #123). to 16 oz(product#456)? And if they pay $5 more they will get 24oz(product #789)?

Right now when I set it up, I can add the option as 12oz, 16oz, and 24oz. But all of them will used the same product ID . Is there a way I can use 3 different product ID for them as they are three sepeate product?

Do we have any commercial module that can benefit this kind of shop?

Thank you for the help.

Hi can somebody please help?

I think I am the same situation as a fashion company. How can a fashion shop set up a line of product? You have size s, M, L, and XL. How do you set that up? Use the same product ID for all of the sizes? What about color? If you use the same product ID, how can you tell which is which? Or how do you separate the ID? Please help. I am stuck....

Thank you.

Why do you need the product IDs to be different? They are not displayed anywhere. Do you mean the product reference number? On the "3. Combinations" tab of the product editor, you can enter a reference number for each of the combinations. This reference number will be displayed in the cart.

Hi Rocky,

Thank you for the reply. I am not talking about reference number..... :red:

I am using your left hand menu. I have set up my product in this way: Category 2= shampoo. Product ID 2=12 oz shampoo, ID 3 =16oz. shampoo, and ID 4=24 oz. shampoo. When I set up the product 2, I also add ID 3 and ID 4 as upgrade. My question is how can I add product ID 3 and ID 4 into the product ID 2 system? If the customers purchase the shampoo 16 oz or 24 oz, how can the system knows to deduct the stock from the product ID 3, or 4 as now they are in the product ID 2? How can I inter-relate them together? All of them are individuate product,
