Thanks for an intersting report ^
It brings back happy memories of driving down to Gib from Jerez to stock up on British foods at the large Safeway (the fact that it was still called Safeway then indicates that this was more than a few years ago!), and smuggle quantities of Tax Free cigarettes back into Spain
This was back in the day when a carton of 200 cost £6 in Gib and £40 in the UK!
