Yesterday I wrote a post on Holiday shopping. It is also a way to save money throughout the year on birthday gifts and other holiday gifts and expenses. If you have in mind people you need to buy gifts for and ideas of gifts you can keep an out for the gifts and possibly buy some of them on sale. There is a post by Donna Freeman about how to build a gift closet.
If you do buy gifts like this it is recommended that you keep track of the gifts you buy so you do not end up overbuying for a certain person.
