Beware of Solar Sites - 3 different sites selling the same stuff

PLease be cautious of this website. http://glensolar.co.za/ With all of the horror stories one has heard with dealing with popup online stores, in discussion with the owner to purchase merchandise....the owner who says he has a small business (with free delivery) but refuses to have a cash on delivery or payment on delivery approach to the items he/she is selling. insist on pay now have delivery later. Their website has cell number only and says online store only. Moreso - 3 different websites having the same products, same approach, 50% off on products, no contact names or addresses...Just saying... Im happy to support them, but trust is earned. Similar website selling the same things using the same approach are: http://www.morningstarsolar.co.za/ https://www.solar-express.co.za/
