Pre 1.2 Chin Sol one free reroll by vendor

"

Chin Sol has had its Increased Physical Damage increased from 75-100% to 150-180% and its attack speed increased to 10-14%, from 5%. Rerolling values using a Divine Orb on this item will also update your item.

I have a level 78 char doing maps (66~69) constantly but yet to see a divine orb.
Just a casual player, although i have 3 exalted orbs which I am saving for future purchases
Is it possible to get ONE free reroll by selling it to the vendor?

Edit: God of RNG is kind to me today, found my 1st divine orb.
