Macbook 12" early 2015 - How much to sell it for?

[yk206]

I have a macbook 12" early 2015 in silver. Everything is in perfect condition except for the battery. I have no issues when using it but it does say to "service battery." How much should I sell it for?

i bought a 8g/512g 2016 on ebay in perfect condition for $390 so i would say around $280-$300
