As simple as it sounds, just need to know when the store opened. Been looking around for 20 mins and can't find anything. A year will be accurate enough. Cheers.

It was whilst I attended Abbeydae Grange, cos remember watching it being built daily... that was 95-00... petrol station was just a disused piece of land.

maybe 98ish?

Planning application in 1995 and the store opened in 1997 according to this.
