Complaint Review: why not lease it

I went to Kmart because of an add I had seen for a lease to own program they were doing , I purchased a 500 dollar computer , paid 89 dollars down plus one payment of 33.00, they told me they would continue to take 33.00 every two weeks for 5 payments out of my account, the kmart employee never told me that I would have to buy out the product for over 200.00 after the five weeks . What he said was I would have the oportunity to buy out the product after five payments or continue to lease until it is payed off, well that is not how this program works you continue to lease and non of the money you have paid goes toward the balance of the total price. You could pay the bi weekly payment until the end of your lease then are forced to either return the item of pay a large amount to buy it out. At this point in time I have paid more than triple what the value is of this item, and if I buy it out now it will end up being more than 5 times the value.  How is this right that this company can get away with doing this ???  They way they set up this payment schedule is confusing to people and you end up paying for months before you realize you are not getting any where with the payments
