Same product - different prices

I need to have different prices for the same product on a product page.

for example:

Product 1

MOD 1 June £50
MOD 1 July £50
MOD 1 August £50

All the product information will be the same. The reason I need the differences is the courses (that is all that is sold) start at different times of the year and we don't want different product pages for each start date.

The selection required would be a radio box.

How can I do this?

Is there a mod for this already?

Many thanks

Use attributes.

In the product entry page in admin, make the product priced by attributes with a base price of 0.

In the Option Names Manager, make an option "Start Date" or whatever, and choose the radiobutton type.
In the Option Values Manager, make values for Start Date of June, July, August, etc.
In the Attributes Controller, add the relevant dates to each product, with the appropriate total price for each, and the prefix set to blank instead of +.

Thanks for that.

Another quick question.

I want to get rid of the sort order (Item Name-Price) and pic (product image) and the word "Max:1" on the main cat page (http://www.cleanchange.co.uk/store/courses-c-5.html)

Which file should I be editing?
