Rent movies once they come out on video, or play a family oriented board game that the entire family would enjoy. Take to the family to amusement parks when the fees to enter are 2 for 1, or if amusement parks are something that you really enjoy doing together, and you go to a park that offers family season s passes, buy one of those. Even if you only get to the park twice that season, you still will have used it effectively. Pack a picnic lunch, and take the family to a local park and spend the day playing outdoor games, and going for hikes. The occasional extravagant trip will be much more memorable, and looked forward to, if they occur irregularly.
Clothing is an extravagance that can easily be avoided.
Instead of buying entire new seasonal ensembles for the family, try looking for clothes at consignment or thrift stores. The clothes that you may find here are only gently worn, and usually in fantastic condition. You may be surprised at how much you can purchase for a very little amount of money. Even if you only buy your own clothing at thrift or consignment stores, you will get great bargains and hip clothing for a fraction of the cost of department stores. You can also try retail outlet malls for designer clothing with lower price tags.
