The price of a LE Watercolor Speedy size 30 is just whatever the market will bear. The 30 will fetch way more than the 35 because the 30 was not released in the US.
I have a 30 and I paid a pretty penny for it because:
I wanted it badly
It was in perfect condition
I'm a real fan of pink and girly patterns for accessories
It goes with a lot of my wardrobe
I'm glad I got it and its a thrill to carry it. To each his own I suppose.
These are great points and I agree. I'm like this with the Mirage Speedy in Noir. If ever I find one in perfect condition, she's mine no matter the cost!
