My very lovely local indie greengrocer.
I'm screwed for good avocados, posh crisps perpetually on special offer, a wide range of Tony's chocolate and a particular soft cheese I've acquired a serious taste for. Not to mention a warm welcome every time, and excellent chat/banter/neighbourhood gossip. And it's a few minutes' walk from home.
On the upside, I'll certainly save money; they're not cheap.
