How much to get your iphone 6 screen repaired?

Not at an apple store

Apple Store will charge you $109 without AppleCare to get your iPhone 6 screen replaced. It will cost you $70 to get OEM if you do it yourself. If you want the whole screen + camera + home button + ear speaker installed, it will cost you about $90. You can either get it repaired from Apple Store or you can do it yourself, it's not very though though. If you need OEM Apple replacements at reasonable price, mail me for more info.

That would depend on stores are available to you.
