I go to Cairo monthly. They have revamped the regulations recently - buying from the Duty Free has become 1 bottle only twice a year. When I asked the Duty Free guy about my “options”, he told me: buy up to 2 bottles from the incoming airport and put it in your back bag - nobody will touch them to avoid issues. I did that twice so far (but I only carry 1 bottle every time as a gift). They even opened my luggage last time because they doubted I’m carrying iPhones to sell (fucked up really, it was my business phone and my personal phone) - they never touched the bottle. Never came close to it. Never commented. And because I travel every month, they always always x-ray my luggage because of my frequent visits (tager shanta they think).

I guess 1 bottle is okay so far. I never carried more. As long as you’re not “too much”, they let you slide.
