Hi, I accidentally bought 2 tins of NAN HA2 and threw away the receipts so I cannot exchange them at the supermarket. I'm letting go of one tin at $40 (retail price is $48) and will give away the second tin which I have opened but hardly touched. Expiry is in 2016 and bought in Singapore. Self collection at Hougang St 92 or Seletar Hills Estate. If interested, pls email me at sereneg_tan@yahoo.com. Thanks!
