It is with sad regret to inform you that because of the Covid pandemic BestLocalData.com is shutting down at the end of the month.

We have lost family members and colleagues and have decided to shut down BestLocalData.com

It was a pleasure serving you all these years. We have made all our databases available for $99 (All of it for $99) for those interested.

Kind Regards, BestLocalData.com Rena
