Just popped into Sainsburys to check out the parking. All the signs (and there are plenty of them ) say 2hrs max for customers only plus the usual cameras and threats of fines!
I wouldn't bother using them. There are lots of parking spaces all along Redbank Road, That's where I will be parking so see you all outside the entrance to Sainsburys at 19:30. I will wait for 10 mins for us all to arrive or better still message me your phone number if your coming and might be a little late. Fingers crossed for some dry weather!
