Only you can answer that. Corals don't have an 'objective' price. It's based solely on how you value those corals. Do you feel that those four corals are worth $62.50 each? What's the likelihood that you could get all of them at once, at that price? Do you want all four?
Corals aren't like gold, oil or other commodities, where there's a well-established market and getting your money's worth is as simple as going to a gold seller or contacting an auctioneer. They're a bit more nebulous, and if you want to resell them, you have to a) Acquire them; b) Successfully grow them; c) Maintain a stable colony for long enough to frag them; d) Learn how to successfully ship live corals. So unless you want to go through all that, the 'worth' of a frag comes down purely to your taste: Do you think you will enjoy them enough to justify that price?
To some people, an Aoi frag is unquestionably worth it (myself included). It's a rare and striking color morph that looks even better as it grows into a large colony. To others, they'll get just as much enjoyment out of a $5 zoa frag as they would from an Aoi frag. But no one can answer that except for you.
Speaking for myself - if I hadn't already picked up some Aois during this sale, I might have gotten that pack, but in all likelihood I would pass. Not that I think it's a bad price - just that for myself, I can't justify buying that many expensive Zoas all at once. I'd rather take $250 and get 5-9 different corals. But that's me.
However, and please note these will more likely not include any Sticks as their value does not match the frags price point.
