Came across these suits from Jos. A. Bank in the USA. Make sure you switch currency to USD. You can order just one of these but this number of items pushes the order into the $19 express international postage zone. There are two suit types, each tailored fit, and each in a variety of colours:
Cotton Twill 2-Button Side Vent Plain Front Suit (~ USD55)

Corduroy 2-Button Side Vent Plain Front Suit (~ USD55)

Then pick two shirts from this list: (~ USD25 each)

Yes, more expensive than Tesco, but much better quality.
+1 from me, especially cos this is sticking it to places like David Jones and Man-to-man. I assume these suits are better quality than the disposable ones M2M sell? Blitz, you ever order from here before?
