Just talked my dealer down to $250 an O (down from $280). Is this a decent price? TX, US

Just curious if I'm getting screwed or not. I saw someone post on here they were getting half o for 135, so I texted my dealer about getting an o for 250. He normally charges $280, i was expecting to pay like 260, 270, but he came down! I was happy, we've had good business. :)
