How many AU can you have on a card simultaneously? I have a citi with 2 slots in the portal that sell pretty regularly. My wife is also an AU on the and is listed as such in the portal. I already have the 2 slots filled, for a total of 3 current AU, and I just got a request to add another. Did they forget to tell me to remove the AU that has already posted? Should I go ahead and remove her before adding the new guy? Or just add the new guy anyway? I emailed the company, but probably won't get a response until tomorrow.
It depends on the card, the company, and your comfort level.
I've had situations where the remove date in the portal is a month later than it's supposed to be, so it's possible that one of your current 2 "commercial" AUs can be removed now.
I've also had situations where the company oversold my slot limit by mistake or in weird circumstances (like a canceled order or a renewal order). Sometimes I bend my slot limit and add the AU anyway, other times I don't and the company finds a different card from some other seller for that particular AU.
I'd generally recommend sticking to what you're comfortable with in terms of the AU limit on each card. If I were in your shoes, I'd also look at when the closing date is on that card, and if possible wait to hear from the company and also remove any AUs before adding the new one. Usually you have a few days between receiving the AU order and the closing date.
If you don't feel comfortable and they've exceeded your AU limit, you can always tell them that and they'll move the order to someone else. I've done that a time or two and haven't experienced any repercussions as far as I can tell.
