Advice on ordering presents for family in USA

[ElizabethinherGermanGarden]

Does anyone have experience ordering presents from the UK for friends in the US? My sister and her husband are in California and although they are over here for Christmas, would rather have presents delivered there so they can travel light. Apart from Amazon, I don't really have ideas and would appreciate suggestions. She is early 30s, relatively new to US so something nice for the house would be good. The only shops I have heard of are in New York from Sex and the City so probably a bit out of date/out of state.

Most US shops will be countrywide, so not just New York. JC Penney, Sears, Hudson Bay etc
My son lives in Canada and I have tried using local shops online, but most will not accept UK credit / debit cards, so you may need to check this out.
I now mostly use Amazan CA as they accept UK cards

I set up a USA Amazon account. Lazy but simple.

House stuff - Bed Bath and Beyond, Target’s nicer ranges like Hearth & Home or Threshold, East Elm, Crate & Barrel, Pottery Barn, Williams Sonoma.

If they won’t accept your CC try PayPal.

Mark's and Spencer deliver in to USA

These are all good ideas. I will take a look at Bed Bath and Beyond - have heard of that one!
