High prices in Singapore

I went to the Challenger Store to look a laser presentation remote device. They should me a few Targus models costing more than $120 each. This was rather expensive, as my friend told me that he bought a device for less than $30 in Sim Lim Square.

I went online to search for this item. A few Targus controllers were offered at Amazon store at around USD 50 (excluding shipping). This seemed to be at about half of the price charged by Challenger. I finally decided to buy another brand and paid less than $20 including delivery charges.

This episode seems to show that prices are really expensive in Singapore! It must be due to the high rental and staff cost.
