Something to send which isn't flowers or food

[fatpatsthong]

I have an uncle and aunt who I usually send flowers to for Christmas. However, aunt (who is a living nightmare) often passes comment on the quality of said flowers.

She also doesn't allow my poor uncle to eat treats or drink much but also they don't appreciate 'things' either.

Wtf do I send (and I do need to send something - one due to family politics and two because despite their nightmarish tendencies they are kind and lovely people I love a lot).

We won't see them so it does need to be something I can get delivered directly. Budget around £30. They are late 60s for context.

Voucher for fancy garden centre?

What about a plan to put in the garden? Or national gardening vouchers?

Theatre tokens
Magazine subscription

A coffee beans subscription?

Charity gift. They would look pretty mean if they moaned about it. Why not ask them though?
With regard to flowers, I always find a local florist and order over the phone. Delivery is usually free also.
