Raise and lower (more for less)

What if you discovered that due to a tax implemented by invisible interstellar aliens, you would have to increase the price of what you sell by 10%? What would you add to your offering so that people would still choose you despite the fact that all of your competition hadn't raised their price? What sort of service, guarantee, design or other free prize bonus would you add to maintain your market share?

And now, having survived that, what if you discovered that you had to reduce your costs by 10%? What would you take out of your product or service so that you could still profitably sell your product even though it must cost you 10% less to make?

Of course, the interesting thing is what happens if you do both at the same time, when there are no aliens slowing down your growth, increasing your costs or hindering your sales…
