@wongzai,
U can check if any of ur relatives want those items; otherwise if the items are still in good/new condition, u may want to donate it to some charity?

Otherwise, just get a lorry to dispose them off; or have a garage sale (except this isn't too common in Msia)

@wongzai,
Ask the furniture shop if he's willing to dispose off the old furniture(s) when he delivers the new ones. Just give him a little extra for junk yard charges
