Hidden Shipping Option available?

[bhtoys]

This may sound strange.... I have smaller items that I know will only be a couple of bucks to ship in an envelope - yet my shipping options start at $15.
Is there a way to set up a shipping option of say $3.00, without it being an option on the Shipping Options page, UNLESS someone tries to check out with that smaller item? So, the $3 shipping option would only show up if they tried to check out with only it in their cart? 
Thanks.

Dunnit.

bo > shipping > carriers > add a new carrier

For the logo I used a post office volume diagram showing width height & depth.
I have not worked-out how to copy an existing courier for all the zones. I had to start from scratch and type "test" as a name and "test" as a delivery time before being allowed to pages two and three to set ranges of volumes, weights and zones.
Half way down each of these pages is

"out of range behaviour" > disable

I used weight but it could be done with volume as well if needed.
This is my summery.

If there are only a few items with low shipping costs, one can also custom-set a carrier for each of these products on the product edit page.
