SQL Vertical table to Horizontal table

Hello Experts Exchange
I have a table of data that I need to group by category, I have attached a Excel spreadsheet with two tables.

Table 1 is how I have the data, and I need the SQL Script to get table 2.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

There is another way of doing this (aside from using "pivot")

    , Shop_Ref
    , ISNULL(SUM(CASE WHEN Category='Cat1' THEN [Price_Paid] END),0) AS Cat1
    , ISNULL(SUM(CASE WHEN Category='Cat2' THEN [Price_Paid] END),0) AS Cat2
    , ISNULL(SUM(CASE WHEN Category='Cat3' THEN [Price_Paid] END),0) AS Cat3
FROM SampleData
    , Shop_Ref
