Complete series box set - region 2

OK, so late last year, the first two seasons are released within about a month of each other. I picked up each of them on their release. Time goes by and there's no word of a season 3 release. Then, the complete box set is released. I assume then, that seasons will not now be released individually as a result of this. This kinda pisses me off somewhat - having spent upwards of £30 on these, I now have no choice than to get the box set. So I will now have two copies of the first two seasons ! Is this a sneaky underhand way of getting extra money out of people in these crazy times we live in ?! Probably so
