Compaq Pinches the Pennies

Due to a "hiccup" in their online purchasing system, Compaq Australia mistakenly put a bunch of their pcs on sale for the ridiculously low price of one penny. To make things worse, before discovering the mistake, they'd actually transferred the money and are now offering the buyers a refund of their money. Even though Compaq says it was simply an honest mistake and they're not at fault, as you can imagine, the buyers want their pcs, not the penny back.
