Great news
Wait for couple of days, the card should be there, as they use 2 days shipping.
Check online if they updated the USPS tracking # (which I doubt). If you don't receive it by 5th, call up USCIS & directly talk with the next level for the tracking #.
I would say you can call now itself & ask for it - saying you want to make sure it gets delivered to you & don't wanna miss it, hence u need to track it
All the best...

I strongly believe that the online statuses are kind of garbage, because most of the times they are out of sync, unfortunately.
In my case on 8/2 status changed to Card Production. On 8/7 I got the approval hard copy but only on 8/9 the status finally changed to Welcome Notice saying they approved the case on 8/3 !!! How can you order card before approving, makes no sense to me.
On 8/24 status changed that Card got mailed on 8/22 - again no sync.
I received the card on 8/25 - and online status still says Card mailed. Normally, as I have seen with EAD/other cases, it changes once USPS delivers the card to you - so again out of sync in my case.
Infopass much required for you, what I feel, as they are dragging things for long, unfortunately.

Totally agree with Pickle & cococacoa -
Moment it hits 3 weeks timeline, you should raise the SR.
My attorney was about to do so on the day we hit 3 weeks, but luckily we got the card dispatch update the same day morning.
Next time when you call the customer service, please don't waste your precious time with the 1st person/level 1 (whatever they call it) - good for nothing, all they can do is read the same thing which even we can see online. They don't have access to check card dispatch tracking number even, so what help they can do with SR.
Immediately ask you want to talk to the next higher level, to raise SR, as it's beyond normal processing times.
Schedule the infopass too, but I would suggest give at least a week gap or something from the day you raised the SR - or else during infopass IO might end up giving the same feedback - 'please wait, u just raised sr, blah blah'.
Atleast you can get the I-551 stamp, to help you during the trip. Keep the trip supporting docs as well, as they might ask to validate.
