Sharing an update on my situation with 7RP - I got a response from them on 2/10 apologizing for the delay (they blamed it on the carrier) and that the insert would be shipped on 2/11. On 2/11 I got an alert about the insert being shipped and got a tracking number, which thank goodness I kept and refreshed everyday. At that point it only said "Label created". Tonight when I refreshed the page again, the tracking number showed "shipment cancelled"!!
I am so disappointed at 7RP at this point I have asked them to refund me. I am extremely underwhelmed by their service at the price points of their products... I suppose my Picotin will go without an insert for now, which I'm fine with... until I have the desire to look for another insert again.
