You can delay as long as you like, or make the claim of 'better value', but it's really only paying lip-service. Every product you buy is an investment. You are telling the company and stores that manufacture and supply it that you agree with what they do. In a case like this, every dollar you spend is condoning bad behavior.

On the flip side, every day you spend above ground on this earth is another day to effect change.
