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.
