There's not really much to say about it - either farm for Mystery Boxes as they do rarely contain tickets, or buy the 6+1 Big Set at 119 Crystals a pop for a garaunteed 3 each attempt. Also, the S rank treasures given to you for free from DevSisters are very rare.

It would just be far easier to buy Cookies directly with Crystals if they require an absurd amount of S rank treasures to unlock and you don't have anything near to that. Get  certain  A Grade Cookies/pet to Level 8. Evolve the treasures and rebuy it. It's 25 Crystals per treasure but it's more of a sure thing than Supreme Treasure chest. The 6+1 Big Set is based on RNG so can't compare to that.
