1: For services, do you shop primarily by price or by reputation? Are you willing to pay a little more for better service or knowledge?

reputation is a big deal. i'm happy to buy knowledge...

2: Which attracts your attention more: always a lower price that doesn't vary or a coupon or other special discount on a higher price?

well, i know that people will be more taken in by coupon/discount stuffs

3: Any cost-effective promotional or advertising ideas you've got or noticed around?

package deals are usually pretty good ideas...
