Christmas/Anniversary gifts


So Christmas is the 25th, and my boyfriend and I's one year anniversary is the 27th. I'm ordering his gifts off of Amazon and here's the problem: we share the account and we get emails and notifications when something we've bought has shipped. So he's probably gonna see what I got him and it's a really huge (something he's wanted, expensive) gift. He said he might order my gifts there too so I might see what he got me. Is there anything I can do?
