The 10 starts at $35 on WS; Montots at $40. My imprecise sense is that the Digoine and the whites (Clous and St. Jacques) went up about $4-5/bottle from 09 to 10. The Montots seems to be holding steady, but at $40-45, it's not inexpensive for a Mercury.
They're probably still fairly priced for their quality, but I preferred them as bargains :)
