Gasoline prices on Monday continued their push toward $3 per gallon, according to The Associated Press. The only question now is when?

Prices have been jumping on the back of a strong oil market where the cost for a barrel has spiked 20 percent in the past month on the New York Mercantile Exchange.

Skyrocketing gasoline prices couldn't come at a worse time for motorists, who will see heating bills jump after the worst cold spell in years.

Oil prices are now about three times what they were a year ago.
