In order to not have a high chance of loosing money in the stock market, you should invest in different company's so you don't loose everything at once if it comes down to it.
Credit cards give a high chance for someone to be in dept for a long time. Someone can pay off a $1000 loan for as long or longer than 20 years. It depends on your credit because the worse credit one has, the more interest is paid.
To comparison shop, the easiest way to do this is by doing it all online. You can go to certain sites such as consumer reports which makes it easy for you to compare a product with the same type of reviews.
You can see the same type of reviews for different products. For example, searching for a tablet, there is different reviews for things like display and ease of use or screen size. Then you can take the criteria that you like and pick which one you like. Then you see what store
You need to be formal and polite when you write a complaint letter. Also, your reason should be some what of a sensible reason. You will be surprised on if your letter is in good format, sensible, and respectful... then you could get some responses
