Got a package from FT today; the first since the holiday. Funny thing is I had 2 orders in that shipped before the holiday (each of which got split into 2 shipments!), this one went in during the holiday, and I got this one before the other two/four!
Another order (still pending) - On Friday, it was waiting on 1 item (restocking), on Sat every item was re-stocking, on Sunday everything was "Ready to ship" except a DIFFERENT item, which is now "restocking"!
However, my advice is also to "wait it out". If you have a big order that's just waiting on one or two items, you can put in a ticket to have them split it into 2 shipments, which they usually will do (although by the time they process your ticket, the missing stuff is likely to have already come in). They have also (on their own) split up shipments for me when an item was holding things back (maybe they'll do that with the order I was talking about??)
