It can be done - but it will take time. Like you, I do not want to spend money on things I do not need, however, I end up shopping some on the web for things that are cheaper that way or more convient. Some examples - I buy the expensive cat food found only in pet stores. I save a trip to the store and get the same or better price by using one of the .com sites. Both green points and clickrewards have those listed so you get points. Try to think of the stuff you would purchase anyway. With some of the sites offering great discounts (particularly for first time buyers) it works well. I also enrolled for alta vista. Another way to get points at clickrewards which is a bit tedious but entertaining is by answering questions for LookSmartLive. For every five questions you answer you get 100 points. For the first one you get an additional 50 points. Good luck.
