ON9 is a monthly shopping event hosted by Le PonPon. The event has a fun premise: every month is a new theme and the participating designers showcase gorgeous items with a twist - one color item is discounted, while the others remain normal pricing. This month is their 1 year anniversary and so they are holding a special event in addition to the normal shopping event.
When you visit the ON9 event, there are little pink and blue cupcakes in most of the merchant stalls. Each cupcake (no group required) will give you an LM and a hint to find another cupcake at the merchant store. Those store cupcakes contain free anniversary presents. It about killed me doing this hunt because while the cupcakes are not difficult to find, the temptation to shop and spend every linden I have was overwhelming. There are some really great stores involved and if you enjoy the ON9 montly event, you don't want to miss out on this hunt.
Congratulations to ON9 for reaching their first anniversary and I hope to see this event continuing for a long, long time to come. =)
