Money Changers in Singapore?

As some of you who've read my previous posts, I'm going to England for medical school.
The British Pound has fallen off a cliff and has dropped yet again, the mid point rate being 1GBP=2.00 SGD.
I highly doubt it'll drop further, in fact, I believe the GBP will strengthen before I leave in September 2011, which is why I'd like to take the opportunity and change for pounds at opportune times like now, little by little before I leave.

I'd probably change £500 2-3 times before I leave, first time being next week?


That being said, changing GBP with POSB/Citi (the 2 banks I've an account with) doesn't give me very good rates. POSB is at 2.04 and Citi at 2.05 for demand draft/TT, even worse for cash. I saw the website for one of the money changers and they were advertising at £1= S$2.03.

Wondering if anyone knows a better exchange rate?

In a seperate note, I bought a pair of shoes and a shirt from www.asos.com, a British online retailer who has free international shipping. I paid SGD 2.12 for GBP 1, just last week!! sigh.....

Anyway, Merry Christmas and a Happy New Year to all!
