A:How much does it cost if I want to have an advertisement in a magazine?
B:That depends on the kind of ads you want to have, for example whether you want to have an ads with colorful pictures or not. Normally, ads in black and white are cheaper.
A:Well, I think we need ads with colorful pictures.
B:But it is relatively dearer.
A:Color advertisement will have a better effect.
B:Yes. Maybe at first you can have a few more small ads than several bigger ones.
A:I didn't get what you said.
B: I mean if it is under the same condition, the frequency you have for your ads is more important than the specification of your ads.
A: That sounds very reasonable.
