Item Drops and Finds Version 2 - Post BB

You can still stockpile them up, and doing the 2 daily quests which gives 5 coins each.
If you're talking about buying the tickets from the NPC, you can actually buy 5 tickets a day, even though she says 3 is the daily limit on how many you can buy.

You can also try PQing; Kenta PQ gives charm, and the scales you trade in for the goggles gives it as well. You can also keep fusing them to farm charm over and over again (if you're an alchemist). Good luck o-o.
