first of all Turkey and Turkish people are awesome :) and they do love egypt and egyptians, and will serve you even better with a wide smile when they know you are Egyptian!
no misleads do not worry,,
as for shopping, you didn't tell where in Turkey you will stay in, but i assum its Istanbul,, if other city i wont be able to help :(
in Istanbul you have many shopping distnations,,
1st is the (Aksarai Laleli) which is like Roxy here in Egypt,, many shops and many streets and small streets filled with shops,
but you have to buy in wholesum,, (gomla) which can be really usefull if you will make an open day when you come back here,,
cheap but nice and good quality closes as gomla,, and not 12, you can find 5 ps,7,9,12 pieses
the other place called (Takseem) its like heliopolis or mohandseen stores, wide main streets with more expensive shops which you can buy one piece,, (and there where the egyptian movie 3okal shot when the police officer came and took him:)
the third place is called (Galeria mall),, it has a big mall like first mall here, or city stars with also much more high prices, around it you will find many shops with reasnable prices,, make up, clothes, lingeri,,
another place called (the covered bazzar or egyptian bazzar!) which is near Aksarai by the way, you can walk to it from there,, which is like khan el khalili here, but different items to buy, but of course the spices and hand made glass have a big part there,, and many mini shops offers jeans and shrits in low prices,, you can say its there (wekalet al bala7 lol)
another mall is offering (stock products) called Olivium mall,, you will find designer clothes with low price cause its stock,,
all places you can go by bus or metro,, Aksarai and Takseem is consider the downtown,, but for Galeria is more far from them,,
just ask the clerk in the bus station (the guy who sell the ticket cause you have to buy it before riding the bus) of the bus number to go each place,, unfortuntly i don't remember bus numbers!!
don't walk alone late before 9 pm,, shops there are open at about 7:30 8 am,, ask the taxi driver how much he will take before you ride,, but its better to stick to bus and metro,,, food is great! really !! stick to turkish food and leave the mcdonalds and pizza for a while!!
above all, give the blue mosque a visit,, its awesome and i was busy shopping to visit it :( it called Game3 ther by the way:)
that whats on my mind for now,, if u need more data please e mail me,,
have a nice time!
Turkey is great and lovely ,, you will just love it,,
