The BP station can already be 10p more than local supermarkets in London, so not a great deal.
A fiver off will bring BP fuel down to the price of other stations. BP always seems the most expensive!
Same problem here too
I've just had a response, so fair play and my £5 has been granted.
Takes 3 days to show in your account . They are having teething troubles , as the first time I tried it ( 2 weeks ago ) my card was declined ! So I rang them and they admitted to problems with BPME at their end and gave me the £5 compensation even though I bought no petrol . The next day it worked fine - So £10 off £40 worth of petrol :D . It appears to be account specific (or maybe once per account ) as I haven't got the offer this time round :( .
