I placed order for the Sony Cyber-shot DSC-TX20 on the 13th December 2012 and on the 19th December 2012 it reaches my HopShopGo US address. Paid HopShopGo US$12.44 (S$15.19) for the shipping to Singapore and I received it exactly on Christmas, 25th December 2012! Didn’t know DHL do delivery on Christmas day itself!
