One list, two people shopping from it
A baby registry has two users who never meet on the site. One is building a list over months and wants everything in the range available to add. The other arrives once, from a link, knowing the parent and not the products, and needs to buy the right thing quickly and see that it is now taken.
Anything in the catalogue can go on the list, rather than a curated registry range
Two entry points side by side on the registry page: create your list, or find someone else's
Nine plain category names across the top, from prams to bedding, since a gift buyer does not know the brands
A wishlist counter and a cart total held in the header, so a long shopping session keeps its state visible
Free shipping over a stated threshold in the top bar, because a gift buyer is deciding whether to add one more thing
A parent can register anything in the shop, not a subset chosen by the retailer
A gift buyer arriving from a link can find the list and buy from it without an account first
The catalogue serves both audiences without a separate registry storefront
