That you stick to essential items and keep them as non specific as possible. DH and I shopped for two vulnerable people this morning under an official scheme. Their requests included 1 litre gin (ok maybe essential), branded tonic, branded cleaning items, organic gala apples, rose and raspberry lemonade, non sweetened organic coconut milk and on and on.
I lost a lot of sleep last night worrying about the additional exposure to the public while searching for half this stuff. In fact we did get pretty much everything but had we been asked for ie large brown loaf, cheddar, packet of bacon, mince, frozen peas it would have been a lot less stressful. This is going to last some months for the most vulnerable, if you or your family are in that category please help by keeping it simple.
Thank you.
