Registry Items...Temporally Out of stock

What should I do? I check my registry every now and then to make updates if needed. I noticed 3 big items on my target registry out of stock! Should I add those items on my Amazon one also? I don’t want someone to purchase it later when it comes back in stock. Are you guys regularly checking?
