Norton 360 different costs

I have only one question:

Why in US Norton 360 v5.0 costs only 25$ (was 79$), but in Romania it costs more than 55€? But in Romania remains the same price...

I mean, it's the same product... If Norton is a single company shouldn't be the same price, the same special offers and discounts?
