No opportunity for me to stock up since I'm getting rid of stuff to be free to travel, but it would be a much better plan to use the money to buy an i-bond which is paying more than 9% interest right now. Of course you have to hold it for a minimum of a year, and if you sell before it is 5 yrs old you lose 3 months of interest, and the interest rate is changed every 6 months based on inflation. But it still seems like an awesome place to put any extra money right now. Unfortunately I cannot because I made the mistake of putting my new address when I created an account on TreasuryDirect, and so their authentication check failed and the account is locked. Apparently the only way to unlock it is to get a bank to provide a signature guarantee stamp on a form for me to send them, but, my banking is online and neither my bank nor my investments have a local physical location, and all the banks I've checked with won't provide the stamp unless I've been a customer of theirs for 60 days and still have active account. I am so frustrated.
