Quick answer: Fans can suggest gifts for your wishlist and you decide whether to accept them. It's a nice way to discover things you might not have thought to add yourself.
Where to find them
Head to your wishlist and click "Suggestions" in the right corner, below your profile icon. Accept the ones you want and pass on the rest.
How to enable Gift Suggestions
Navigate to your Wishlist Settings, scroll to the Wishlist category, and look for the "Gift Suggestion Settings" at the bottom of the page. Toggle on/off and hit Save Changes.
What to check before accepting
A few quick things worth looking at before you say yes:
The merchant. Make sure it's a trusted shop or brand you recognize. Partner and verified merchants mean lower fees and more reliable fulfillment. Be cautious with smaller or private sellers like Etsy or eBay unless they're explicitly supported.
Availability. Check the item is available in your country.
The details. Make sure the price, taxes, and shipping costs look right.
That you actually want it before it gets purchased.
Staying safe
You're never obligated to accept anything. If a suggestion makes you uncomfortable, you can block the user.
