Remember minimum $200 purchase (before discount) to get free shipping and 20% off.
Not as good as the 3+3 offer but pretty decent to get the discounted packs and free shipping.
So 2 packs of the marsanne packs equates roughly $13 for normal one, $15 for museum and $25 for 1927. 4 bottles each.
Or if you want just the 1927, you can go 5x1927+1 bottle cheapy ones or the cane cut. Roughly around $30+ for the 1927.
