Actually if she sells a used Iphone which is worth ( new ~150 $ ) then you shouldn't pay more then needed. You could also go to a store to buy an Iphone ( also used once ) and there you get them cheaper.
Say 100 $ and spend her a cinema evening

or maybe go to a restaurant with her. ( shall be cheaper then 150 $ tho )
