>>54985114>50 Incubators (store price: 150 - realistic value: 50-60)>50 Supers (store price: 200 - realistic value: 70-80)If you value them at 50 and 70 respectively, then this is a bad deal since the Incubators are 2500 value and the Supers are 3500 - so it's 1000 coins overpriced.
If you value them at 60 and 80 then the Incubators are 3000 value and the Supers are 4000 value - which adds up to the exact 7000 that Niantic are quietly begging you to top off your Pokecoins for.
Personally I'd only value incubators at all if you're desperate for stardust unless there's a very specific egg event on which wants you to hatch a great deal of 7-10-12KM eggs in a short time period.
Remember that eggs are always a gamble.
