What do you get someone who already has everything?

When someone has everything they want, the failure mode is buying them another object. They'll receive it politely, store it, and eventually donate it. The fix is to leave the 'object' category entirely.

Consumables. They get used, appreciated, and don't add to the pile. A bottle of something genuinely excellent (wine, whisky, single-origin coffee, premium olive oil), a curated hamper from a quality source, or a chocolate selection from a real chocolatier. Repeat-purchase quality is the test.

Experiences. A meal at a restaurant they've mentioned, tickets to a show they'd never book themselves, a tasting tour, a class in something they're curious about, a hot air balloon, a track day. RedBalloon and Adrenaline cover most of these in Australia. The booking is the gift — they don't have to organise anything.

Considered upgrade. The better version of something they already own and use daily. Their wallet is fraying — give them a Bellroy. Their headphones are old — give them current Sonys or Apples. Their kitchen knife is dull — give them a real one. The signal is 'I noticed what you actually use'.

What never works: another candle, another book unless they specifically wanted it, another decorative object, another tech gadget unless it solves a specific problem you've heard them complain about.
