(NB: The link will only be valid today, after which the URL will change to http://www.deal.com.sg/deal2 and so on, which incidentally strikes me as stupid (a permalink would be much better) but I didn't raise USD$1 million in November, so what do I know?!)
Screenshot taken on Thursday, 3rd February, 2:05pm:
"Time left: 10 hours 55 minutes 10 seconds"
This would place the closing time of this deal at 1am on Friday, 4th February.
Yet, a screenshot taken on Friday, 4th February, 12:17pm shows:
"Time left: 12 hours 43 minutes 11 seconds"
This would place the closing time of this deal at 1am on Saturday, 5th February - 24 hours later than what we were told, yesterday, was the original closing time.
Note: this is the same deal
So far I've not seen this sort of deception on the other group buying websites.
