4/5 Egg at Champ should be no more than 500M. 600M for Ult, 700-800M for Mega depending on the digimon.
5/5 Egg at Champ should be no more than 1T.
Data, should be no more than 1M - 1.5M, depending on the type of data.
Evoluters should be no more then 100M. No exceptions.
I'm so sick of the people cash shopping items and charging ridiculous prices for them. There's this one vendor charging 400M for a single evoluter. The same vendor also charges 3.5M for a single piece of data.
I very much agree with what you said about the ap digi eggs, prices are certainly ridiculous and with the normal data which you get from scanning the eggs i think price range should be 750B - 1.5M of course depending what type it is.
But about the ap bought ones, i myself bought some with my ap and yes i tried to sell some for 3M -3.5M but in all fairness i think its a reasonable price because real money went into acquiring that and i think its right to charge a little extra for that, i mean come on its just 2M extra won't exactly kill ya. But this is just for the ap data cause everything else people are defiantly way overcharging on some things.
