Booking airport parking through easyjet, beware of the booking fee.
 

Just booked a bargain fare Luton-Basle return for £40.98 all in with easyjet and out of curiosity clicked on the link offering 20% off airport parling. The price looked resonable but on the last screen before you pay a £1.50 booking fee had been added.
Before going through with the transaction I checked with BCP who I have used in the past only to find their prices the same but with no booking fee plus they give air miles.

Before this turns into a "lets have a go at the locos" thread I would like to point out that before easyjet this trip would have cost me nearer £400 as it does not include a Saturday night.
