Yes they may. For those looking to see how prices change over time, just keep checking back on any given event from the date it was first available, until the event date. Typically, as the time and date of any given event gets nearer, ticket holders selling their tickets on the Gigsberg marketplace may lower their prices to sell off the inventory of tickets they have in a lower timeframe. A fair number of sellers prefer to get at least some money at a cheaper rate than to completely lose their money on an unsold ticket.
