Poupee girl - Piyo Catcher and Free Market

I'm a total newbie when it comes too Piyo Catcher and Free Market but after 3 Piyo Catcher events, I've gained some experiences and know better what I should do:

• Don't play Piyo Catcher, no matter how cheap it is, no matter how pretty it is and how much I want it, playing Piyo Catcher is a bad idea. Unless I've tons of Ribbons around waiting to be used, which never happens anyway.
• Stalk the Free Market 1 day after the Catcher is released and aim for the rarer items. The common items will get dirt cheap after about 4-6 days but the rare items may increase in price if people see how hard it is to get them. It's better to try for a price that is slightly higher than the Catcher's price. Buying items on the first day is a bad idea since it's hard to know what is a good price, unless I get lucky and get an incredibly low price.

I've probably wasted over 2000 Ribbons for not thinking carefully and jumped in the Catcher knowing nothing. But at least the future looks better now ;)
