For Fujifilm prices, go to www.fujifilm.com.sg They are more expensive though. The handling fee varies from place to place. Some charges $2, while most were not willing to reduce even for large amounts of prints.
You can try Photohub at Raffles Place. Quite good results for me so far. They print 3R and onwards, including 8R. The prints do get cheaper according to amount of prints. But you've got to check with them in terms of what medium they accept. You can call them at 5330433.
