I have a site that has some pages for products that rank well in the SERPS. I would like to start selling them online. But... I don't want to create another page/post that will cannibalise ranking from the original page. Is there any way of telling WooCommerce to use an existing page for a product page rather than creating a new one...? If not I suppose I could move content to the WooCommerce product page and 301 the other, but I'd rather have it the other way around if possible. There's only a couple of products to do it to so not too hard I guess...
