Stingy me complaining again. I asked the local photo developing shop what's the biggest they can develop on site. They said 15X10", for NT$150. So that's 1 square inch for NT$1. However, for the 4x6" photos, they charge only NT$6 each. Means for each square inch, it costs only $0.25. May be I should order a bunch of 4X6" photos and piece them together to make a 15X10 one?
