Bargain for everything. Whatever price they say to you, you should not pay more than 50% for it. Trust me, they act like they cannot afford to go so low...guess what, they're still making a huge profit.
This is a typical scenario in Egypt. You stroll in the tourist markets,and a hawker calls out to you. He says he will give you a t-shirt for US$5. You are tempted,and walk into his store to see it. You then find a good-looking shirt and hand him 2 bucks. Then he suddenly says "no,this is a good quality shirt.It costs US$17.It's this one that costs 2 Dollars",handing you a lousy China-made shirt. You then have to pay him 17 bucks,look for other items or leave the shop,disgruntled. So please, NEVER BELIEVE ANYTHING THE HAWKERS SAY. You'll be disappointed.
Unique Suggestions: Simply be prepared for surprises, and you''ll be fine. Don't be scared by proprietors' aggression in pushing something. It's OK.
When shopping for souvenirs eg. Khan el Khalili, try to have a summary in your head what to buy, and for whom. If you buy all the things from the same person, you'll save a lot of money. I started to remember late that I wanted one more glass pyramids, one more obelisk, one more... and ended up spending twice as much I would have spent.
Unique Suggestions: Laugh it off! Souvenirs aren't that expensive after all :]
Be careful when buying small stone carvings and papyrus. They will always tell you that those are authentic but most of the items they sell in cairo are fake ones. They are not real stones and definitely not real papyrus..so try to pay the price for a replica.
At the bazar, any cab, actually wherever you buy something. NEVER pay the price a product is offered. We nearly everytime managed to bargain to the half price. Guess if you're good you'll even get all the stuff for a quater. Threat to leave(it often works). I guess it's clear that you FIRST bargain the price and then consume.
Certainly Cairo Tower offers a magnificent view but the price is quite high: Its 40 E.P. entrance, 50 E.P. include is one soft drink or 70 E.P. when a meal shall be included!
Everything they selling around the pyramids is 10 times expensive then on the other places. All souvenirs and everything else you can buy somewhere else. The same things.
