What you actually pay for something is at least twice the listed price because of the energy, time, money needed to set it up, learn, maintain, repair, and dispose of at the end. Not all prices appear on labels. Actual costs are 2x listed prices.
你为某样东西实际支付的费用至少是标价的两倍,因为还需要花费精力、时间、金钱来设置、学习、维护、修理、善后。不是所有价格都写在价标上。实价会是标价的 2 倍。
