Im using the table shipping module, where "up to 3 kg" equals
say 10 dollars in shipping cost. This works fine.

However, any item wider than 120cm incurrs an additional
"bulky package" fee at the post office. Lets say 1 dollar.

What I would like to do is to identify these products and
make their shipping cost (weight) + 1 dollar.

Is there any way to do this? I did not find any suitable modules
in the download section, nor through searching the forum.

I suppose an clumsy way would be to just modify the weight
for those specific products, and I tried 20B as in 20 kg "bulky"
but obviously that did not work.

Any ideas? This dosn't seem too compex,
but Im not that well versed in the Zen architecture.

Sincerly
