I never knew anyone who actually traveled that way, but it definitely existed and maybe still does. I suspect that traditional shippers like DHL or Fedex have supplanted most of the business, as well as the airlines' direct cargo divisions themselves.
In any case, for ten pounds of candy, you're probably just looking at a costly airmail bill. I feel your pain...
I traveled that way a couple times in college from the US to the UK (which was in the mid-90's). The flights weren't free, but they were really cheap (I think one year I paid $150 and the other time I paid $100). I had to forgo any checked luggage space, and the courier service used the 2 free bags (I was allowed at the time) for their cargo. I never ended up taking anything through customs except from paperwork, which I had to provide to the customs officer.
Given how heavily my plane ticket was, whatever was shipped using my baggage entitlement was expensive.
I would think for the OP that just shipping the items via the post would be cheaper.
