Dry-cleaning

In preparation for my business trip to New Orleans (thought I would casually drop this in here...), I finally got three of my suit blazers dry-cleaned. And discovered a dry cleaners just round the corner from the flat. I had prepared myself for sky-high London prices - so I was very pleasantly surprised when it was only £5.50 per jacket.

Not that I actually know how much dry-cleaning costs elsewhere, but it seemed rather reasonable. Or did I get ripped off??
