I would really love to get Worms Armageddon as Worms Reloaded on Steam is a bit of a mess, particularly when it comes to online matchmaking. Console port aaaaargh.

Anyway, I don't have my old CD anymore and I'd like to buy it for download. HOWEVER, the link to "Buy" it on the official W:A site does not work. The webpage times out every time. Can someone fix this or is the game just not being sold anymore? If not, then where can I get it? I don't want to be a dick and download it off Piratebay, plus I don't think I could play online in that case...

You can buy a game bundle including Worms Armageddon from Amazon (http://www.amazon.com/Worms-2-Armageddon-Pc/dp/B000E23XNA) or Mastertronic (http://www.mastertronic.com/productSoldOut.asp?pid=267&productLabelID=1) (former Sold Out Software).

The only official download version that existed was the Trymedia/Trygames one, but that one wasn't compatible with the beta updates and was thus stuck with an ancient version number.
AFAIK, it isn't sold anymore anyway.

Team17 have closed their online store.
In recent years they have mostly sold the Sold-Out/Mastertronic versions.

As CyberShadow mentioned, I'd go for the double-pack which includes Worms 2 too.
Choose whatever retailer is cheaper in shipping. Amazon is probably the more convenient, while buying from Mastertronic might be faster.
