Went to check out accessories for the HTC Desire HD on Expansys AU and came across what they call their "Deal of the Day" (didn't know they did those). $498.72 is the cheapest I've seen this for, even compared to eBay. Staticice had the cheapest at $564. This one is described as "HTC Desire HD (T-mobile start-up logo,Multilingual)".
Expansys offers "free GST" for AU orders under $1000, so when I tried to add this to my cart, it removed the GST and applied $15 postage —> total of $468.38 delivered. I think that's a good price for a feature-packed smartphone that's not even a year old!
Oh, and just adding their T&Cs:
1. Offer cannot be used together with any other promotion offers & vouchers.
2. Bank Transfer only
3. All rights reserved
I'm not familiar with these "Deal of the Day" things on Expansys, so I would assume this sale will end quickly, so hope this helps those searching for this phone.
edit: Sorry, guys. I didn't realise Expansys had such bad reviews! Mods, feel free to delete if needed.
