Is that alcohol genuine? Kwa wale mko alcohol business, where can one get the cheapest genuine alcohol at wholesale??
For Electronics, Luthuli Av, though you need to know who sells at wholesale, ignore the shop attendants, they will rip you off. Try a guy called Sameer, +254 710 676525. Check the prices for what you want online/any other shop, then call him, compare prices, go have a look at the product then pay.
For Phones, buy from the Wariah malls in downtown luthuli not Upper.
Use this Somali, Kanvinho: +254722603615, again check the price elsewhere, call him, go confirm the product at his shop and pay for it. Have used both countless times and referred people to them. Good luck
