Why do stores and manufacturers use mail in rebates? A scam, or is there a way to use them effectively?
Unfortunately too many companies view a Mail in rebate as an unwelcome cost instead of as a customer interaction issue, and it gives the company a bad reputation when someone gets stiffed on the mail in rebate, and it also has basically ruined the concept to a large degree. Many people will simply regard the rebate as worthless and evaluate the product based on the full price - killing what the company wanted to get out of it (Rich Seller hit the nail on the head), which is why you see "instant rebates" etc.
Below is an instruction that describes a task. Write a response that appropriately completes the request.
