selling them for anywhere between $40-$80 over the current value

Crazy...

Anyone else that can sell me ~40$ in bitcoins?

To be fair, he probably listed them at the price they were a couple of days ago. Right now BTC is steadily dropping in value compared to the USD. It's gone down about $10 since I started looking for ways to buy BTC locally (about an hour).

I'm still trying to find other ways to get some bitcoins at a fair exchange rate.

Deozaan:
or does one usually own multiple addresses?

Yes. A wallet contains many addresses. However, once you start getting up into the thousands of addresses, it's a good idea to create a new wallet to "clean out" your old one.

How do you do this? Just send all your bitcoins to a new wallet? Wouldn't that essentially link all those addresses to one address (the new one) all at once?

I just signed up for Coinbase and told them all my darkest secrets to verify my identity, only to find out that if I try to purchase some bitcoins right now, the soonest the BTC will be available to me will be next Tuesday. :(

EDIT: I added a credit card and now I can buy $25 of BTC instantly, once per week. Still not quite good enough. :(

Just signed up with CoinJar to have a play, here's their current exchange rate based on current Bitcoin.info @ US$317.80 = 1BTC

Does anyone here use Bitcoins?

Let's me link my bank account (AU or UK) to direct convert ... now if only I had some money in it  ;D

Their Hedge option looks particularly interesting since BTC is currently dropping.

Deozaan:
I was fascinated by the concept of the proof-of-work that miners have to do, so I started working on a little test of something of my own:

SpoilerI wrote something similar to what I understand the Bitcoin mining requirements to be. This is not mining real bitcoins. It's just a simulation of mining Deocoins!

It has been working on hash #10 for quite a long time now, so far with no luck.

EDIT: It finally found hash #10. The reason it took so long was because 1) it was difficult to find and 2) while I was waiting for it to find it, I did other things with my computer, and the application was set to pause if it didn't have focus. When I finally realized my mistake, I changed it so it wouldn't pause when not focused and it finally found the result a few minutes later:
