I need some help/clarification on selling downloadable products. I need to limit the download of a product to one time over a 5 day period. I assumed if I set the "Max number of activations" = 1, the system would limit the download, but I'm now thinking that only applies to serial number activation? Is there a way to limit successful downloads without using serial numbers?
 
Also, what happens if a user purchases a quantity of 50 downloads - do they receive 50 separate email links?
