Starbucks doesn't franchise their locations. Besides, as someone else stated, they've closed most of their stores here since they were hugely unpopular. I've only seen a couple of them in capital cities. There was already a huge network of independent cafes before Starbucks came along and they serve a superior product to anything that Starbucks could offer. There is a coffee chain here called Gloria Jean's which is franchised but they're pretty terrible.
Buying an independent cafe would be cheaper than a franchise and, depending on the location, has the potential to be more successful but is also a lot more work.
