When I was in Singapore, I went to Alan Photo located in Sim Lim Square. It's a mainstream store that carries camera, lenses and accessories.

When i was there, they were giving out free Nikon umbrellas due to a promotion they were having. One of the employees actually ran out of the store to find me and give me my umbrella after I'd walked out not realizing they would give me one. I still have that umbrella.
