Last min grocery

Yup, just came back from the nearby supermarket. Earlier on, i was reading thru the supermarket's weekly special circular and i saw Maggi Mee at 10 for $1. Then i exclaim, "Ya hor.. There's no maggi mee for tmr"

What happen is, we have 2 kinds of maggi mee.. The super cheap cheap and expensive kind. The cheap ones are these nissin ones and we boil them to add the soup we cook. Maggi mee and watercress soup goes very well together. We have some soup leftover for tmr lunch but ran out of cheap maggi mee. So we dragged our feet out to buy.

What's weird about this:
1) The cashier wave a pack of mee 24 times to enter the price for 24 packs? OR
2) us buying 24 packs in 1 go?
