Selling epic shiny pidgeot.
Instant sell is 350k.
To clarify things i have gotten multiple bids for 250k ingame which i dismissed because i had the exact same price back when i caught him as a pidgey. So naturally when i take him to 100 and ev train him that should cost more. I might settle for less than the instant sell price though.
EDIT: sold ingame for 2ms and 30k.
