A limitless choice of extraordinary craft beer at max. e1.00/500ml. My local bottle shop stocked maybe 500 kinds of beer.? I'd go once a week, and randomly choose 'c5 beers I've never had before'. Then I'd enjoy them and consider them, and then I'd visit BeerAdvocate and see how others found them. I did that every week for three years.... yes, maybe almost all 500 beers
Lidl/Aldi.
250gm tubes of mustard/mayo/tartare that cost e0.29 each
Smoked salmon as a staple, not a luxury. Ditto fresh mussels.
20 kinds of cured ham
Hot fresh sliced and loaded roast joint of pork kebabs (down the local market, the stall was called 'Carnivore' lol)
29 cent deodorant. (we brought, I don't know, maybe 30, wedged in a box we knew would stay upright whilst in transit).
M+S ready meals. In the UK there are maybe 1000 options. I can eat a different gourmet meal every night for three years (though I really miss the curries (Indian, Malay, Thai, VNese... they really have it covered).
This could become a veeeeery long list
