Wild bird seed and wild bird food difficult to buy as all sold out with many items

With the widespread problems widely with panic buying at various stores and shops nationwide in the UK at present. I’m getting short with wild bird seed and wild bird food and believe it or not as I’m trying to buy the items for my bird feeders and bird table there’s also widely a shortage of the items for buying bird seed and bird food completely sold out. I’m self isolating for 12 weeks as mentioned in another thread. Has anyone else had problems like myself with buying food for there bird feeders and bird table.
