You obviously don't want to deal with this person.
There are few people that are willing to sell their coins at a discount (even if it is small), and if you need bitcoin now then it would be advisable to offer a small premium to encourage people to sell to you that might not otherwise be interested in selling.
And obviously you should almost always use escrow unless you have a lot of experience trading as it will protect you from scammer
