I booked using V30 code it offered me decent discount on business parking, 60/- at heathrow for 17 days. (long stay with this code was 52/-)
Excellent price for well off site parking. Make sure you arrive in good time, depending upon the terminal and time of day, your journey could be lenghty.
Seems a fair price for Heathrow I am used to Manchester prices, next July 17 days Meet & Greet for £39 or £2.30/day. As I posted in this thread yesterday https://www.hotukdeals.com/deals/airport-parking-aph-15-off-1733606#post19899093
why cold just over £3/day where else can you park cheaper,I used to park on someones driveway and with return transfer I was paying £4 a day as a frequent user!!!
