Which is why SLS had been blacklisted for a couple of times. I remember a time when my Vietnamese friend from Australia came down for a visit and I brought him to SLS for cheap electronic. There one of the salesman (forget from which shop) looked down upon our sloppy outfit and when we wanted him to show us one of the camera on display, he told us, "You want to buy or not? If not don't waste my time." (or something to that effect)... another shop told us simply that his camera is "very expensive" and thats it.
Well... to say the truth... I have never had a good experience in SLS, so not going there anymore... even those 'reputable' shops can sometime try to cut you.
The only advise I have is to do a good study into the price and function of anything you want before going down... and if you are chopped, I and many of the good people in this forum will appreciated that you post your experience here so that others might learned and not be the next victim. Because unlike many of the "more experience" members here, many are newbies and do not really know the price or what to look out for when he/she wanted to buy something.
What is more important was to perhaps give us the name of the 'black' shops too and so we can avoid them totally.
So I for one, thank TS for bringing up this issue. If only the name of the shop is also present then it will be the best.
