Open the wish's ⋯ menu and choose Edit to change it or move it to another list, Clone to copy it, or Delete to remove it for good.
On a computer, point at the wish's card to see its ⋯. On a phone, it's next to the wish's name. The wish's own page has a ⋮ menu instead, and tapping the wish itself only opens its details. On someone else's list, what you can change depends on your access level: see "What can each access level do?".
Steps
Open the wish's ⋯ menu and choose Edit.
Change what you need: the link, name, price, currency, Where to add or Notes for the gifters. For a from and to, switch Price to Price range.
For Wish priority, Tags, Description or Images, tap More settings.
Tap Save changes.
Changed the price and it went back? See "Why isn't the price on my wish updating?".
How do I move a wish to another list?
Open ⋯ → Edit, change Where to add and tap Save changes. A wish can move to another wishlist, but not into a collection.
To copy it instead, choose Clone: a New wish form opens, filled in from that wish. Pick a list in Where to add, or one of your collections, and save it. On a shared list where you can add wishes, Clone works even on wishes you can't edit.
How do I change the order of my wishes?
Drag the cards on a computer; on a phone or tablet, use Reorder from the ⋯ in the bar above your wishes.
Tap that ⋯ (not a wish's own ⋯) and choose Reorder.
Drag each wish by the handle in its corner.
Tap Finish Reorder.
Clear any filters first. While one's on, Reorder doesn't show, and dragging a card shows “Clear all filters to reorder items”.
How do I add my own photos to a wish?
Add them in the wish's edit form, under More settings → Images.
Open ⋯ → Edit and tap More settings.
Under Images, tap the + tile and choose a photo, or drag one onto the tile.
Drag the photos into the order you want. The first one is the main photo.
Tap Save changes.
To remove a photo, tap it, then its trash icon. The main photo also sits at the top of the form, where tapping it offers Replace and Delete. The form shows how many photos a wish can hold.
Can I get a deleted wish back?
No, deleted wishes can't be restored: there's no bin. The Delete wish box warns “This action cannot be undone.” before you confirm.
Deleting a wish also removes any reservation on it, and the person who reserved it isn't told. If you got the gift, mark it as received instead: see "How do I mark a wish as received?".
Tips
Put the wishes you want most at the top. Your list shows them in the order you set.
Happy with any model within a budget, or asking for a gift card? Switch Price to Price range so gifters know what to spend. Want price-drop alerts on it too? See "Why isn't the price on my wish updating?" first.
Make your clearest photo the first one, since that's the photo on the wish's card.
