i TOOK A RISK

I went to my neighbourhood to post a letter. Then when i was abt to leave, this man came down his van and stopped me.
.
Said he had a Home Sound Theatre System for FREE to give me ! BUT i only need to give him some COFFEE MONEY ! .
.
There are 2 of them actually. They are installers or delivery guys lah. Apparently, they went to their supplier's warehouse to get 8 sets of the Theare Systems. BUT the supplier warehouse blur blur given 12 sets. And if they bring back to their boss, their boss will BENEFIT from these 4 sets. So they rather BENEFIT themselves lor.
.
The BRAND is CARLSON AUDIO - CA6300-F !!!! .
.
I offer $400 lor .. but they asked for $500 ..
.
They even opened a receipt for me, and then even give me their NRIC, also copy down their NRIC number on my receipt and given me their HP number. I TRUSTED and given them $500. One of them said I havnt given him my contact. This sounded even more sincere rite???? SO i given him and i rushed off. Surprisingly, this guy called me after 5 mins, said anything can call him. But remind me not to sell the system if not will get them into trouble etc.
.
so, I TOOK THE RISK of $500 SGD to buy this system !! But i dun need it. Decided to sell it to my brother who just married. BUT then, i also duno is this system working or REAL or watever !!
.
Hahahahaha i dun wan to appear on papers being one of the DUMB singaporeans being cheated leh !! LOL
.
But hours later, i called this guy, he answered the fone and tell me this is really a good system etc. Becoz i said the material looks lousy! He said these are PIANO finished material .. i mean the material are those piano wood material.
.
Anyone advise me?? .
