Slight change of plan. I have found a shop in Coventry that sells all sorts of nice edible and/or drinkable goodies, and they will deliver free if the order is over £10. She llikes things like Stem ginger, ginger biscuits, kiwis, etc, so that might be a less expensive option.

I would think if I explain the circumstances, they could find a nice box to deliver it all in.
If I bought a bouquet of flowers at the local market, I would get a hugely ginormous one for £10.
Thank you for all your help.

I will bear in mind all the suggestions, in case I need them sometime.
