Add fields together from MYSQL Query

[Mr.x]

Good evening everyone,

Im not 100% sure if this is going to be done in MySql or PHP, thought i'd have my best chance here though.

I'm working on a script that calculates a users profits from daily purchases. Basically what I have is the table where all the purchases are which is named `purchases`, within this is all the activity and information which includes the date of purchase and costs.

What im hoping to do is find all purchases by seller using seller_id and then add up all of their sales (money/cost the buyer paid is named `price`) and devide it by 2.

ie. Select `price` FROM `purchases` WHERE seller_id = "*seller id session here*" AND date = ".$day."

Then add all of their "price" fields and / 2

Any help would be greatly appreciated.

Thanks Alot,
