How duty free is actually used
Travellers think about duty free before they travel and buy in a rush at the gate with limited time and limited information. Pre-ordering for collection solves both, and most operators do not offer it. Allowance rules are the other constant confusion: what can be carried, in what quantity, to which destination — questions answered inconsistently by staff and rarely published anywhere a traveller can check before packing.
What we build for a duty free operator
First, pre-order with collection at a gate or on return, which captures the decision made at home rather than the rushed one at the counter. Second, allowance information by destination, the question every traveller has and nobody answers clearly. Third, accurate stock and flight-linked offers, since relevance depends entirely on where the passenger is going. Fourth, price comparison against local retail, because that is the only reason the category exists.
