I ordered a NUCLEO-G474RE directly from ST yesterday. I could only add one to the cart, whereas I wanted two. When I recently bought two NUCLEO-F334R8 I didn't encounter this.

So apparently there is limited stock, and someone else that wants one can get it despite me. That's fine; I'll go back later and get another. It's great to see at least one damn company thinking this way.

BTW, they're providing free shipping for a limited time!
