:) I'm not even there yet! Still trying to find a house, which I can tell you is excruciatingly difficult.

The list is based on averages, from 5 different supermarkets each a with their own products. The products are examples, not the actual price of 'that' product; as some stores don't have exactly what you need. It really depends on the kind of food you buy. Certain Asian products are very inexpensive, but imported American or European foods can be costly. An example is Italian Salame (pork) or even Kellogs. You can get the Kellogs made in Saudi, or the Kellogs made in the US. Price will vary obviously.

Like I said, it's indicative, not fullproof, but it should help a bit.

Anyway Good luck with your move. :)
