The Amazon Wish List can serve many purposes.
It can also be used as an online gift registry for many events, such as weddings, birthdays, babies, and others, which you can then use to share with your friends and family.
You do need an account to use Pinterest, but it's free, and the boards are easy to share with anyone you choose.
Gift-givers will know exactly what you or your child wants, so no one will be disappointed, and the gift-giving process becomes easier and more efficient for everyone.
That said, in addition to its that lets you add items from anywhere on the web, you can use your phone's camera to send items directly to your account while out shopping.
If someone else tries to buy the same item, they'll get a warning that it's already been purchased.
