Use SKU instead of ID

I suggest you use the product SKU instead of woo’s ID. A marketer is probably already using the SKU in other product datafeeds. Making a new feed and looking up Woo’s sort of random ID would be a pain, and other than being a number assigned by woo, the ID has no meaning for the business.

Also, it doesn’t make much sense to send the value of the product to Facebook for an AddToCart. Doing this will mess up conversion value tracking because an AddToCart is not a sale, and has a much lower per visitor value than a sale.
