If you can't find any other activity to share with them, try shopping with limited cash and no credit cards. That way you can't overspend on impulse. How much you can safely spend while still working toward your financial goals depends upon what your goals are and where you are financially. Finding the best value You can find high quality and low cost in the same product. Conversely, paying a high price is no guarantee that you're getting high quality.
Cars are a good example.
Whether you're buying a subcompact, sports car, or luxury four-door sedan, some cars are more fuel efficient and cost less to maintain than rivals that carry the same sticker price. And when you evaluate the cost of a product or service, you need to think in terms of total, long-term costs. On the surface, the Convertible appears cheaper. However, the price that you pay for a car is but a small portion of what a car ultimately costs you. If the Convertible is more costly to operate, maintain, and insure over the years, it could end up costing you much more.
