In the quest to save money on weekly provisions, many dedicated shoppers fall directly into the “just one more store” trap. They visit the local supermarket for general pantry needs, drive across town to a big-box warehouse for bulk paper goods, and stop by a specialty ethnic market for cheap produce, all compressed into a single exhausting afternoon.

In reality, they are burning through expensive fuel, wasting precious hours of their weekend, and inviting countless impulse buys that completely wipe out the marginal savings they worked so hard to achieve. I will examine when chasing grocery deals stops saving money.
