This seems to be the account every MSC gets at some point.
I have seen them state to ONLY purchase the required pizza and then blast emails with a high reimbursement amount in the email title to get your attention.
The instructions change from every MSC. I have written the Jon ID inside the box with a sharpie. Then I have another that wants you to write it on a printed out piece of paper and set it next to the box. They all have a minor variation on how they want it done. I also have two MSC's and the one that delivers to me is always snatched up before the emails even go out.
The other MSC for locations outside of my delivery range will change it to a pick up when they have a bonus on it and need my services.
