Here is an alphabetised list of things I've been unable to buy (usually due to lack of stock) in my local Co-op recently:

Asparagus
Aubergines
Avocados
Broccoli
Cauliflower
Courgette
Garlic
Mango
Sea bass (or an alternative white fish)
Sesame oil
Sweet potato
White onions

Plus the incessantly surly staff and high prices. It's rubs. Bare rubs.
