What is your postcode?

Does not recognise our postcode??
On 17th November 2020

When I export to KML and import to Google Maps, it links all the circles together and creates a big tangle of lines. Is there a way to complete this transfer taking just the circles and not the lines as well?
By Nik on 17th November 2020

Bob, its just below the map. The first text box.
By Free Map Tools on 28th October 2020

I will only travel a radius of 1.25 miles in order to purchase my pyjamas (otherwise you end up spending too much on petrol, and must sacrafice certain other aspects of the pyjamas, such as a nice soft material ie. polyester). So this tool came in very handy when deciding where to get my next set of pyjamas from. 10/10 would reccomend if looking to purchase pyjamas.
