It's an AVS mismatch that the merchant mistook for a decline. It happens pretty often and it happens exactly as Sara described, being automatically refunded ten days later.

Yep, that would be twenty THOUSAND dollars if they did that a thousand times. A large bank has two BILLION dollars on hand on any given day.
Actually though, your thinking is it's a $20,000 loan. The federal funds rate is 0.15%, meaning for the bank to borrow $20,000 for ten days costs them $0.08. Yes, eight cents to borrow $20,000 from another bank.
let's look at that in figures:
Do commit fraud for:
8¢
when you have:
200,000,000,000¢
No, when the bank is a little short they just write a $10,000,000 check on their federal reserve account. Borrowing $10 million costs them $41.
You want to know what DID happen? An AVS mismatch, in all likelihood. Some merchants treat an AVS mismatch as a decline, but it's not. ePassporte used to do that. When the AVS doesn't match, the transaction will be flagged as such but it's still a perfectly valid transaction and the money is held out of your account. The merchant sees it's marked as mismatched AVS and THEY decided to ask you to check the address. (Or they didn't see it at all, just misplaced it.) Then when they neither complete the charge by marking it shipped nor refund it, ten days later the bank automatically refunds it.
