I have a sneaking suspicion that buying national foods & drinks is normal

I was at a not-much-variety inconsistent supermarket (not as weird as it sounds) buying Aussie foods and solid Aussie drinks, that means the coffee's in granules and the tea's not liquid tea (there's no Aussie tea, this Lipton one is Kenyan) and I was thinking "if you can't get it at a not-much-variety inconsistent supermarket you shouldn't get it from Woolworths", the result is there's no Delta Cream biscuits, there's only TimTam, TimTam caramel and TimTam Murray River salted caramel, I chose the latter, there's also only Kingston, raspberry shortcake, chocolate ripple, assorted creams, and lemon cream, as well as Murray River pink salt gourmet crackers, Fantastic delites, regular Fantastic rice crackers with French onion, cheese and onion, and sour cream and chives flavours, and barbeque, both the latter and the former.
Of course, because it's Aussie, and as for coffee they have Vittoria coffee bags, Robert Timms coffee bags, a medium-small Bushell's gourmet instant coffee, Nescafé Blend 43, Nescafé Blend 43 espresso, and Nescafé Blend 43 mild roast, I chose nothing special or non-ordinary, just the original, regular Nescafé Blend 43. As for food I chose a frozen vegan bolognaise and rosemary sea salt lavosh crackers with mini-tasty cheese slices. A few hours later I went back in the store and bought fresh parsley, two Vitasoy unsweetened soy milk Protein Pluses, chicken breasts, 3 cans of crushed tomatoes, and a packet of sliced mushrooms, then a little even later on I bought some kind of Whisper's dry white wine from the liquor store, the above supermarket has vegetables, chicken bites, spicy chicken wings, Bonsoy, Sanitarium almond milk, Sanitarium unsweetened almond milk, Vitasoy oat milk, Vitasoy rice milk, Vitasoy soy milky, and Vitasoy soy milky low sugar. I wasn't tied into special, except national, foods and drinks, and I have a sneaking suspicion that's normal.
