Charges may be cut at two car parks in Walsall town centre for motorists who use them for up to two hours.
Private operator NCP reduced all-day fees at almost 500 spaces at Freer Street and Station Street earlier this year.
It means drivers now pay a flat rate charge of £3. But bosses say they will consider in the new year whether to reduce the fees to £1 for drivers who park for up to an hour, and £2 for those using the car park for two hours or less.
Under the plans, the changes would come into force at the Freer Street car park first, but would then be rolled out to the Station Street site.
Derek Kirkwood, cluster manager for the parking operator, said: “In January, we will be looking at whether to make the charges more flexible and charge £1 to those who park for an hour and £2 to those that park for two hours.”
The all-day fees reduced by more than half to £3 at the 120-space Station Street site last month.
Before that, the charges were £3 for up to two hours, £5 for four, £7 for up to six hours and £8 for a long stay, with reduced fees at weekends.
Mr Kirkwood said the move would attract shoppers and offer a boost to local businesses.
