I bought around 15m2 of mixed Indian brown sandstone cobbles from Rock
Unique, who also supplies flags in many sizes:

Gorgeous stuff, excellent prices, and great company to deal with.
Ordered on Thursday July 28, and delivered from London to Edinburgh on
Monday Aug 1.

The delivery set me back £135 in addition to the cost of the cobbles,
however it still was far cheaper than anything I found locally. Local
suppliers said 2-4 weeks delivery for similar stuff, nevermind having to
buy "full packs" from for example Keyline!!!

I'll be happy to drop you a picture of my project if you like (still
have a bit to go though :-) .
