TSQL - Select multiple rows into single row. (Master / detail tables)

I am trying to put together a query that summarises a month worth of items in a detail table and I'm struggling a bit.  Basically what I want to have at the end is:

      Item 1 - 15 - £10
      Item 2 - 1 - £12
      Covers deliveries 1232, 1234, 502.  Dates 01/01/2000, 01/02/2000, 01/02/2000

The item rows are easy, but I'm not sure how to put together that final row.  Tables being worked with are something like this:

      Summary Table:
      ID
      Total
      Date

      Detail Table:
      ID
      SummaryID
      DeliveryNumber
      DeliveryDate
      
I can do a simple select to return all detail rows required (SELECT [DeliveryNumber], [DeliveryDate] FROM [DetailTable] WHERE [SummaryID] = @SummaryID) but I need to get this into a single row and formatted as closely as I can to the sample above.

Any solutions?

Here's a little known technique that can be useful when flattening out row values from a column

Declare @v VARCHAR (1000)

SELECT @v = 'Covers Deliveries: '

select @v = @v + DeliveryNumber + ', ' FROM [Detail Table] WHERE SummaryID = etc
