You can wait and get the eggs later if you need to. Its not as if the eggs will ever be removed from the prize shop. The eggs are buyable from the Prize shop for your prize tokens from perticipating in each contest.
You can always wait and buy an egg later.
that is at the very least a month and a half wait. waiting that long just so you can get a pokedex entry just isn't practical.
Support. If you really think of this from the old players point of view (or why not newer ones who have achieved Arceus), decided to have a little break from the game, and then come back. I was lucky enough that my return was at the end of the current Tournament season, but all of us are not that lucky. It might seem a little time to wait for some people, but it really is not.
This game is alot of fun when it comes to melan hunting pokemons (frustrating aswell, lol), and that is the reason for me atleast to come back each day to click and hatch those eggies :)
