Hmm... Both the Nikon D300 and the Nikon AF-S DX NIKKOR 18-200mm f/3.5-5.6G ED VR are discontinued. Assuming Photocam kept them all the while, and assuming that prices have not moved since they were discontinued (i.e they retain their lowest publicity published street price), then:
Nikon D300 dSLR - S$2,000
Nikon AF-S DX NIKKOR 18-200mm f/3.5-5.6G ED VR - S$1,000
Therefore, the total for the 2 items is S$3,000. S$200 for the rest of the items may be a little costly, but well, I won't be so hasty to call this a scam yet.
TS, have you tried to go back and get a receipt? Also, can you clarify if the products you purchased were new? Or were there indication that they were 2nd hand?
Ya, the TS please clarify
