Found a huge amount of Taylor’s of Harrogate Nespresso compatible coffee pods available at Waitrose Saxmundham. These have been discontinued on their website so I would assume it’s nationwide.
The following were available at Saxmundham (usually £3.00)...
Praline Especial Brazil - Roast 8 £1.55
Cacao Superior Colombia - Roast 7 £1.39
Decaffe - Roast 7 £1.29
Hope this helps someone.
