Upgrading RAM doesn't seem to be possible

I have a 2-month-old Core 2 Duo which I purchased with 2GB, because this eejit didn't read the specs properly and didn't realise this was 2x1GB chips. Now my 2G5 has suffered terminal death, I am using the MBP as my main system and, as such, would like to maximise the RAM. However, I seem to be at an impasse. I cannot find a single 2GB module anywhere (I'm in the UK and I don't have a credit card so ordering from abroad isn't possible). If I'd ordered it with 1GB, then I could have upgraded it to 2, that wouldn't have been a problem, but I cannot upgrade to 3.
Incidentally, could someone with the technical knowledge about these things, please enlighten me as to why the slots are asymmetrical. Surely, if the RAM in these things has to be installed in matched pairs, then the maximum ought to be 1, 2 or 4, not 3.
I wish I'd saved up a little longer and ordered it with 3 from the outset! Gah!
Why does Apple do this to us? Either ship the damned thing with a single 2GB module, or allow it to be upgraded with a single 2GB module. Either that, or set the maximum at 4 and sell a 4GB (2x2GB) kit!
So does anyone know of anywhere retailing a single 2GB module, or am I stuck with 2GB?
btw, I wish there were UK-specific forums, as I know that the majority of posters here are (probably) North American.
Yours, frustrated,

please enlighten me as to why the slots are asymmetrical.
It's because of the Intel chipset used in the MBP C2D used particular memory addresses that come into conflict if you have 4GB memory installed. Even though you can actaully install 4GB (2 x 2GB) RAM you will only ever get around 3.2GB of that. So, to stop the "where did all my expensive RAM go" questions, Apple just limits you to 3GB. Which I think is fair enough.
As for being assymetrical, the MBPs do not suffer from the same performnace issues as the MBs. Most because it the integrated graphics processor that requires the symmetrical RAM. In the MBP there is dedicated VRAM so this is of no importance.
Why does Apple do this to us?
They didn't… as you said yourself, you didn't quite read it right. While maybe Apple could have made it clearer all the information was all there in front of you.
Either ship the damned thing with a single 2GB module
This would be a good CTO option for them to offer although I think they don't simply due to the short supplies of the 2GB SODIMMs.
So does anyone know of anywhere retailing a single 2GB module, or am I stuck with 2GB?
While Enthanee recommended that you go with Apple, had she read it correctly should would have noticed that Apple only sells 2GB RAM for the MBP C2D as 2 x 1GB SODIMMs. It's what you already have. Apple currently does NOT sell 2GB SODIMMs as a standalone product.
So, What I would recommend is that you try calling Crucial UK…
http://www.crucial.com/uk/
… and see what they can do for a credit card-less person like yourself for the Part Nº CT613260 (2GB SODIMM for the MBP C2D). Same goes for Kingston…
http://www.kingston.com/ukroot/
… although with these guys you'll probably have to call them to find a reseller near you that can order it for you. The part number you need here is KTA-MB667/2G.
