How long does it take CGC to open a WalkThrough package? 1 1

[FrontStands]

CGC marked my package as delivered, (I believe 3 days ago.)
I'm wondering how long it normally takes CGC to open a submission from this tier, just to make sure they saw the "WK's" I had written on the box.
My submission number: 9994544296

Good afternoon,

Thank you for your message. We do try to open the properly marked expedited packages as quickly as we can, however, due to the high volume of these expedited packages we have coming in, it can still take some time.  I would say if you don't see anything by next week to reach out to our customer service department at 877-662-6642 or by email at submissions@cgccomics.com.

Thank you!
