I've lived in the UK for twenty three years and am yet to have heard of "Makro". From what you describe, there is no equivalent to Costco in this country. There's a store called "Costcutter" which is ubiquitous - I don't know if there's any link there.
I used to love cleaning, but my OCD has since gone away and, if anything, my house can be a little bit of a mess.
I don't own any casettes, though, unlike another recent poster here in my age group, I own well over a hundred CDs.
I'm going to kill this discussion by asking if anybody has read Jorge Luis Borges - then I'm going to go to bed.
