Soundbar + 2 speaker set-up

[Patrick Bateman]

I'm a million miles from an expert in this field- ideally looking for something basic like a soundbar along with a couple of tall wireless speakers to go behind the sofa.

Does such a package exist for anywhere close to £100?

Had been eyeing up this sound bar as an inexpensive improvement over the standard TV audio-

Just checked there, stretching the budget would be one way to put it!

Ignoring the 2 tall speakers just now, would it typically be easy enough to add 2 wireless bluetooth speakers at a later date or would these things always have to be part of a set to work?

Not a clue, hence asking if it's possible somehow.
