1000000 exp ticket swap

Why would anyone trade in 67 15k exp tickets for 1mil exp ticket? 67x15000=1005000.

Maybe I am missing something here but that is a rip-off.

It consolidates the tickets. Losing 5k is negligible in that regard.

You lose 5000 experience...so just use them as you get them?

On the JPN version, there are also events where the Swap Shop gets a 20% discount, meaning that it drops down to 54 15k Tickets for the 1 Million, a 190k EXP gain.
