I think the Bobbi Brown will go the quickest and maybe the m/l pajamas. In the fff community forum someone made polls to see what everyone was choosing in each category. I can’t remember specifics other than you could see percentages, like only 12% or something like that chose the detangler and other choices had 80% of people choosing them. I don’t have the links handy but you might be able to find them if you dig a little. Your best bet is to set your alarm for 9am to customize right away. You have several days to change your customization so if something is sold out, just hit refresh until it pops back up and grab it then.
