I'd like to take a monitor with me as a checked baggage, but it is an international flight with one change so it seems quite risky. So I would like to buy one at Colombo Airport duty-free shop. Do they sell monitors there? Would it be cheaper than buying it somewhere in Sri Lanka after arrival?
Also I'd like to buy some HRM watch, either Polar, or Garmin, or FitBit, or smth. Do they sell such things in airport duty-free shops?
