How to create and display a list of 'specialed' products.

[Don Gould NZ]

I'm having trouble understanding how I'm meant to set the system up for specials.

I have 20 products that I want to put on "special" (discounted) for 6 weeks from 1 June to 15 August.

Each product is to show the 'normal' price and the 'discounted' price.

Eg:  Bar of Soap - Was $5, Now $3

Each product has a different discount.  They're not, for example, all discounted by a set percentage or dollar value.

Eg:  Bar of Soap - Was $5, Now $3
Cake of Soap - Was $5, Now $3.50
Bottle of Soap - Was $5, Now $3.95

I only want the 'pre-tax' price displayed.

I have tried using the 'Override' feature, but this seems to override the 'Tax included' sales price.  I don't want that. 

I looked at the Tax & Calculation Rule area.  Surely I don't have to set up 20 rules, one for each product on special, do I?

I also want the product pages to display the old price (crossed out if possible) and the current special price.
