Konga is a scam!
Their ads are not upheld when you get on their site and they fabricate all sorts of lies, to justify charging you for delivery, when their ad clearly states that you will not be charged beyond a certain order amount.
The products are clearly used, second hand and of extremely poor quality.
It is better to go to the shops to search out what you need because most of their products are more expensive than in the shops...
What a scam!
