It is easy to default to the cheapest option available, but the lowest price is rarely the same thing as the best value. Looking past the price tag, even briefly, tends to lead to fewer regretted purchases.
Material and construction are usually the clearest signals of how long something will last. A well-stitched seam, a solid hinge, or a fabric that resists wear will outlast something that simply looks similar at a glance.
It also helps to ask whether you would choose the item again if you saw it for the first time today, rather than relying on the momentum of an existing purchase decision.
Buying fewer, better things is rarely the cheaper option upfront, but it is consistently the better one in the long run.
