Say no to expensive uniforms and commissions paid to schools

Why do we have to purchase logo polo shirts for PE that are expensive instead of supermarket best value. Why are Secondary schools getting commissions at our expence. Say no to only one supplier who rip us off with hidden postage and packaging. We are in a double ressesion and need support. We should not feel discriminated and persiquted by over priced uniforms. Our choice of style should not be dictated by schools. Say no and take it to parliment.
