A friend of mine just loved to go to tanning sessions to have a nice skin color during the entire year. After her third month of paying for these sessions at a tanning center, she decided it was time to save up money to buy a tanning bed for herself, and store it at some bedroom of her house. She thought that it would take her some time to be able to buy a tanning bed, especially as she was not going to drop out her sessions until she bought one. She had calculated that in 6 months she would be able to raise the money to buy herself a tanning bed, but fortunately she was able to buy one only three months after of making up her mind as she was able to find some great tanning beds for sale at unbeatable prices. She was so happy when she learnt that the model she was looking for was being sold at a great value. As soon as she found it on sale she purchased one of these items and stopped attending to the tanning sessions at the tanning center. By now she had quite a pretty good idea of how she should use the machine to get the color tan she wanted.
So she started to use her new tanning machine day after day obtaining some very nice results on the skin of her color. But one day she thought that the machine was not working well as one of the tanning bed bulbs had stopped working. She soon learnt that these have a life expectancy and should be replaced as soon as they stop working. But it was nice to know that these bulbs were sold at a very good economic price, so she did not mind at all. She bought one bulb to replace the bulb which was not working any more and bought two more tanning bed bulbs just in case more bulbs started to malfunction.
