I'm rather lucky where I live; ignoring the abusive employer, I have three different supermarkets (US English: grocery stores) within a reasonable distance of my home. I shop at all three; one is good for basics, but doesn't do produce well, one does produce exceptionally well but can be tricky to find basics in, and one has more esoteric stuff (such things as cheese with flavour, beer with flavour, steel-cut oats for my breakfasts, and so on) that the other two don't carry.
Unfortunately, until today, all three of them lacked something I wish was more common: peeled shrimp/prawns. Shell-on, sure. Tail-on, sure, but you know what? Like everyone else on the planet, I don't eat the tail. It has no place in my food.
Fortunately, today I found such shrimp. They'll be a regular item as long as I can get 'em.
Now, if only I had any idea how to cook swordfish...
