I went to buy a CMOS battery, in one place they wanted to sell me a single battery for 50 pesos, and in other place they sold me a whole strip of 5 batteries in 30 pesos.
@keisuke last time I went to buy one, the 1 pack, 2 pack, and 4 pack were all the same price xD bought the 2 pack because that's all I needed but still funny.
granted that i only needed one battery, but CMOS batteries always come in handy
