Leaking the week before release is the standard for every single album. 5 days before release isn't really bad.
+ almost every album is put in a few stores for sale earlier by accident; when Soundscan first week sales leak there's always a few copies from the week before that showed up as bought.
Example:
Over 2K copies before official release week sold.
Oh wow, I didn't think it'd show up like that on official sales reports. that's cool
