While shopping613 is right about the makeup (it is very expensive here), it is not advised to bring shampoo and conditioner.
You can buy good brands like Head and Shoulders, Pantene and others here – even though they are more expensive, it is worth it because they are formulated for hard water, unlike the stuff from the States.
As far as cream cheese – I have no idea where shopping613 is, but buying American-style cream cheese is no problem here – either stop in at a Brunch Bagel, or go to a supermarket that sells cheese by the weight – it’s called gevinat shamenet.
Clothing is more expensive here, although I disagree about the online orders – I and lots of Americans I know buy very good quality clothing here, you just need to know where to shop!
