Old memories, new popularity Aside from the massive popularity of the Nostalgia Lunches, domestic convenience store chains are also paying attention to this virgin market. Starting a couple of years ago, one after another they started offering different kinds of local packed lunches, starting a "biandang war," -one would offer theirs for NT $ 40, so a competitor would drop theirs to NT39, all promoting their lower prices.
老回憶，新流行就在台鐵懷舊便當翻紅之際，國內的連鎖便利商店也注意到這塊處女市場，從前年底開始，紛紛推出不同口味的國民便當，並打起「便當大戰」，你賣四十元、我就賣三十九元，完全以價格促銷。
