Savings, bursary, scholarship money lost to a 'buy 2 get 1 free' online scam.
IT WAS, to them, too good a deal to pass up - buy two 32GB iPhone 4s at $350 each and get another one for free.
The model sells for $1,048 without a contract.
But after the three sisters sank in about $5,000 of their savings, along with two other girls, they realised it was a scam.
It started with an ad on Gumtree Singapore - a classified ads website - which a classmate showed to 17-year-old Tan Hui Ting.
"She showed me her iPhone and said she bought it from this 'buy two get one free' deal online," claimed Hui Ting.
"She's been a good friend for five years so I trusted her."
