Travel Agent's Advertisement....

These few days when i check on the travel and tours advertisement in the straits time newspaper.. i came across some of the travel agencies are advertising their taxes in this way.. they advertise all the tour fare and on top they just print "taxes fr$150 - $670".. I called up NATAS and enquiry about that.. and NATAS told me that these travel agencies did not follow the Advertising Authority's standard guideline.. I then gave a call to the advertising authority and was told the travel agency has a guideline to advertise.. these travel agents are not following the guidelines and they are investigation into it..

Taxes from $300 - $690.. how would consumers know how must the tax for the destination they wanted to book.. ? Confusing for consumers...
