www.seeedstudio.com - my favorites - located in China, 3-4 weeks from shipping date to arrive to Israel. sells lots of cool stuff, very cheap shipping rates (free for orders over $50)
www.iteadstudio.com - similar to the above, different products and prices.
www.mdfly.com - never bought from them, but also carries a nice selection
www.siliconray.com - ditto.
iteadstudio and seeedstudio carries a PCB fabrication service at ridiculous prices that really makes home-etched PCBs a thing of the past ($10 for 10 copies of your 5cmx5cm board). I prepared a spreadsheet with the exact prices for each size and quantity.
www.adafruit.com - run by Limor Goldstein (her was a student of my wife in the university).
www.sparkfun.com - nice products, wide selection, but more expensive than seeedstudio, and shipping is also more expensive (starts at $8). carries a 'free day' every year around january where they give away $100,000 to $200,000 one day a year in the form of coupons (up to $100 per individual) and crash their website.
last, but not least:
www.ebay.com - the best place for electronics component shopping if you can accomodate the month delay. If you look for basic components, always try searching for '5pcs, 10pcs, 50pcs, 100pcs' as it will dramatically reduce the price per item (100 LEDs at $3 including shipping, for example).
http://www.sollan.co.il - will do 1-day shipping
http://www.aristock.co.il/ - S. Tel Aviv - Har Zion 26
BNC Universe - 13 Lavanda Yalec (www.yalec.com seems to be broken)
non-electronics local stuff
Arad metals - on salami st. (take a left from us)
Metal rack universe - 26 Chlenov st. 036870920

Here is a 50-value 0805 resistor kit (40 resistors from each value) http://www.ebay.com/itm/SMD-0805-50-Value-Resistor-Kit-40-ones-of-each-value-/390401976068?pt=LH_DefaultDomain_0&hash=item5ae5c56704 Total cost is $9 including shipping. Here is a 50-value 100pcs each 0603 resistor kit ($9.95) http://www.ebay.com/itm/5000-pcs-50-Value-SMD-Resistor-Kit-0R-10MR-5-0603-/320473282437?pt=LH_DefaultDomain_0&hash=item4a9db23785
Besides, haven't we said we don't buy "perishables"?
More: You can get a brand-new 100MHz digital oscilloscope (Rigol DS1102E, google it) at $460 including shipping from tequipment.net I bough mine there. Add to that ~250 NIS for VAT at the post office. If you will google for Rigol, you will see it's a chinese brand name, as much as the chinese can have one. One of the low-end LeCroy/Tek/Agilent series (forgot who) is a rebranded Rigol, if I'm not remember.
The DS1052E (50Mhz) used to be a hacker's hit because it's actually a 1102E, with a firmware that enabled an analog filter. Some firmware hacks turned the scope into a 100Mhz one. Later revisions made this harder, and a dramatic price reduction on the 1102E made this no longer worth the effort.
As for Logic Analyzers, nothing beats the Open Logic Sniffer. http://www.seeedstudio.com/depot/open-workbench-logic-sniffer-p-612.html?cPath=174 It is fully open-source, and it has seen great advancements in terms of its FPGA design as well as its front-end software.
I have one at home and it is indispensable
here  is a spreadsheet with all the PCB options in seeedstudio.com and iteadstudio.com, both of them working with thee same manufacturer. For each quantity, I've marked the deal with the best $/cm^2, so for example at Quantity 10, you will get a relatively cheaper deal at 10x10 than for 5x5. The traffic-light like marks gives you the general feeling if this is good price or not, while the yellow background is the cheapest in each quantity and type.
I originally updated the price a few months ago, but I don't think they have changed. Update: I've actually spent the last 30 minutes verifying the prices, and updating where's necessary
