Maybe you shouldn't call first thing in the morning.
At all my Targets that dept is pretty far away from customer service so it's not like the people can actually leave the dept and go walk over and scan something and come back to the phone.
Also, I agree about sometimes the staff doesn't realize it b/c the signs say one thing but scanning says another. If you're calling too early the employees are discussing what needs to be done - that's what they were doing in the holiday aisle this morning while I was there. The night crew girl was telling the person taking over her shift what she had done and where she had left off with the work so the morning person would know what needed to be done. I don't think they cared how much anything was - they had to do what needed to be done - which is condense that Xmas stuff.
Give the employees a little time to get settled and get the word out among each other that it's 75% - remember it's not the markdown team who is looking for specific items to markdown.
