Always give your potential customer a choice, so that they pick from "Your offer A or your offer B" rather than from "Your offer or a competitors offer".

Why red pyjamas or blue pyjamas?

When our kids were little they would often not want to go to bed. My wife's technique was to say "Would you like to wear your red pyjamas or your blue pyjamas?" Magic! By the time they had chosen their pyjamas they had forgotten about not wanting to go to bed. Our children, who are now adult, now say that their mother was the "Queen of spin" before spin was invented.
