Price Ordering...

[Solti]

We have big store, around 50000 products, some of them don't have prices. We set it up the default product ordering to be the price. As we see the default price ordering is low to high which is good, but how can we put the products without price to be last in the list not first.

Fast replies are very welcome, i think it is gonna be a simple task for expirienced developer.

The version we use is 2.0.20b. We use it only as catalog, no cart functions + a lots of others stuff is off.
