Depending on the quantity you are going to be using, and your location (i'm going to assume Australia), you are going to want to check a few places.

1) Local Electronics Stores - often have hit and miss selection, and the prices are terrible, but they are quick.
2) Digikey/Mouser - They are going to be the cheapest (especially in bulk), and have a large variety, however I'm not sure how their international shipping is. ( http://www.digikey.com/ ) & ( http://www.mouser.com/ )
3) Sparkfun - The most support, and great for finding sensors, prices are decent, and selection is fair. https://www.sparkfun.com/

In terms of the prices on the site you listed, they seem on the high end of what I have seen elsewhere (then again I'm not up-to-date on the strength of the AUS Dollar)

Hope this helps!

ebay, 'nuff said.

i don't think i've paid more than £2 for any component so far from ebay china, that's a PIR, an ultrasonic sensor, 400 pin headers, 40 breadboard cables, an LCD, 100 LED's, 100 resistors, 5 shift registers, a stereo amp, 20 switches...

the only thing you've got to be careful with on ebay is powered usb hubs, they're largely rubbish.

I have used Futurlec with success: www.futurlec.com
Another good source is Tayda Electronics: www.taydaelectronics.com

You can also get free components from TI and Atmel as samples.

It depends on what is the purpose of buying electronic components. Actually in USA, the expenses of warehousing, manpower is really high, so the prices of components in USA is not low. For example, if you buy components from Mouser and Digikey, you would find their price is really high. But the advantage is that they can provide the largest selection of components for you. If you are building something is not so complicated, I suggest that you can buy from Asia, like China. There are so many electronic components store in China providing compoenents at competitive prices. I build my hobby projects by using components from China. They are cheap but they are os good quality. I usually easyeda.com for my PCB layout and then buy parts from its online store LCSC.COM. Of course if you are a maker, I recommend seeedstudio.com in China. They can provide you modules at reasonable prices.

I've found that some of that is true from my experience. For instance, while Mouser may have capacitors that are 10 cents each in volume, if you buy only a few the price will be higher.

What I like to shop are the mom'n pop electronics stores. Some retired guy does it for a hobby, or a small biz operator does it from a low-cost facility. One such shop is BGMicro (bgmicro.com). I often find parts on that site that are cheaper than the same or similar thing in the big warehouses, even in relatively low volume.

I second the Futurlec idea, they were the first place that popped into my head. Amazing prices, on some things. Also just Aliexpress or eBay, assuming you know the market and what is or isn't a bargain. I haven't found one good source for everything that's absolutely guaranteed to be the lowest price even 75% of the time, you have to shop around. Price search engines like https://www.google.com/shopping and http://www.pricewatch.com help in some cases.

But what do you mean by electronic components? To me that means resistors, capacitors, ICs, transistors. Maybe you're talking board-level or higher. And do you want 1 of something or 10,000?

Let me add, since nobody else has, http://www.allelectronics.com/ and http://www.goldmine-elec-products.com/ but again, you have to know the market. Sometimes they buy something they shouldn't and they're stuck trying to unload it for the next 10 years without losing too much on it. Also http://www.herbach.com/ and https://www.sciplus.com/ Those have been around since the 1980s at least. For cords and adapters http://www.monoprice.com

This is a North American company, specifically, so jmarshali should have mentioned that fact.
It matters, because most/many PI users are NOT from the US!

please don't use this thread as an excuse to spam part re-sellers from all over the world, this isn't a free advertisement site.
I will have to lock the thread when it becomes one, and I _will_ start deleting posts then.

Also know that Yeeho (the OP) posted this same subject twice, so I already had to delete a duplicate.
