Arran Pilot is on the Bridgend Garden centre site but notes that their suppliers have managed to find some and are due in week of 3rd Feb.. I've got my seed spuds from them for years, always very good value and an excellent range although that has declined since 2019! They also have Anya, a cross between Desiree and Pink Fir. Ambo is a Irish-bred variety and I've found that several others, including my favourite Maxine (also Irish) are no longer available. Another Brexit negative. My order from early November, along with onion sets, arrived about 10 days ago.
