My order of 18 boxes from mid-February arrived at the post office today. They shipped well after 21 days on an AmEx charge, so not all AmEx orders that sit idle for an extended period are dropping.
I saw the note in my POBox but wasn't prepared to carry them home so I left them there. I'll get them on Monday. I might actually use them to invest as new money at a bank rather than just redeposit them. Seems like it might be time for that and I've got the cash to invest.
