Singapore Expats

I need to ship a few boxes - probably around 8-10 from singapore to thailand. ( The standard size household boxes that are usually used for packing ) Does anyone know of a cheap carrier that can send these - time is not important so land or sea would be ok.
thanks for any advice

If you want it dirt cheap and don't mind if some boxes disappear, or are damaged, or opened and valuables removed, then there might be some dodgy-looking little stalls at Golden Mile (the Thai's meeting point in Singapore).
For more reliable, but reasonably priced service, go to Singapore Post.
