Nice, but cheap Mother's Day flowers/plants, by post?

[ChesterTown]

I was sure this must have been done, but can't see any recent threads
Does anyone have any recommendations for something that can be organised on the Net and posted for Mother's Day, that preferably looks expensive but costs less than £20?

Interflora do boxed flowers for 20GBP delivered (sorry, pound sign buggered on laptop) as do Moonpig. Obviously they are not arranged but I send them to myself sometimes when I fancy flowers in the house and they are pretty good.

That sounds promising - thank you!
