How do I tell him

So I’m starting a craft shop and I have the page up on FB with a few of the items I’ll be selling posted. A cousin asked about if he could order one. I didn’t give him a price yet though because I was still working on them. However my mom and grandma decided to write one off and give it to him as a wedding gift as he is getting married next month and none of us can make it. I was chatting with him today and he wouldn’t tell me which one he wants so I can put it off to the side as I’m putting the others in a craft show at church ⛪️ next weekend. I can’t tell him his aunt and cousin already paid for it
