As comments have suggested, Polski Sklep Żubr Abingdon are temporarily overloaded with donations for Ukraine.

R&R have a cellar full. So they have the first lorry load to be taken by a Polish lorry to the Polish / Ukraine border.

There are other ways to donate financially from Ukrainian to Polish Charities to UK Charities. UK charities have launched the DEC humanitarian appeal. The UK Government will match donations from the public pound-for-pound up to £20 million.
