Amazingly after 18 hours, these are not yet all taken; if the top link for a product download is already claimed, you can move on to try the next one for a given product, and so on, and claim that.
Also, do keep in mind that any potential bonuses from the sale are not applicable to people who download one of each of the free downloads. Those extra bonuses - which quite bluntly are looking highly unlikely to reach the goals by now anyway - would only apply to bundle purchases.
