(EXAMPLE) Say I'm selling soda. And this soda comes in a 100 oz. Super gold bottle, a 20 oz. glass bottle, and a 2 oz. cup. Same product, but obviously vastly different prices and containers.

I want to market the 100 oz. to one demographic, and the 2 oz. to another.

Would you create 3 different product pages, or one page with separate size/container attributes? And if you create 3 different pages, is it going to be a problem SEO wise as the content will be almost duplicate (the description of the soda will always be exactly the same)?

Hope this makes sense :)
