How much space have you got? Potatoes are good for clearing ground, but take up a lot of space for something that you can buy cheaply. Have you tested the soil. You need acid soil for blueberries, so if your soil is on the alkaline or neutral side it will not grow blueberries well.
Assuming you are in the UK, most garden centres will have seed potatoes (small tubers ) and so on in the spring.
Ken Muir and Chris Bowers are good sites for getting fruit trees and strawberry plants.
