Allow Plenty of Time
Shopping with a kid takes more prep time than shopping alone. Toddlers have to be buckled into car seats. Young sons may need more time to tie their shoes; older ones have to get their hair just right. Allowing time for these routines ensures that everyone will be happy and relaxed at the start of the trip, thus making it more likely that they'll end the outing feeling the same way.
It also leaves more time for making thoughtful, informed buying decisions. Whether you're shopping for school clothes or toothpaste, you may want take a moment to discuss price and brand names, or to consider whether the item is likely to go on sale and whether you can do without it until then.
Our next point also deals with buying decisions. Money is power, as they say. Read on for a discussion of how to wield it wisely.
