Hi there are a few different 3 corners. Is it the one in Naama by Garden Palms or the one in Hadaba? Naama wouldnt pay more than 50le but they will ask for about 140le min and they wont drop the price. Some say go outside airport and flag taxi down but its such a hassle. I used to use one for £5 but he is busy with trips and has stopped doing transfers. Another Company I have used charges £10 up to about 8 people each way so will prob go back to them.
