Small gift ideas for an online friend

[Twoweekcruise]

I am a member of an online support group for a health issues I have.
I made friends with another sufferer about 18 months ago.
We get on really well and WhatsApp each other throughout each day. We are support for each other with our issues.
She lives 6 hours away so I can’t pop a Xmas pressie round but would like to send a little token of my appreciation for her support over this time.
Does anyone have any ideas what I could pop in with her Christmas card?

I would. buy something "neutral" such as chocolates, flowers or wine. Maybe have a look at the M&S gift box selections? With a nice thank you note attached.
Or do you want to spend a smaller amount? If so, how much? Maybe a paperback novel that you think she would like.
