And at the time of posting you could have got it for £19.99 with the voucher
Now regarding the cold votes that is a bit tricky.
Yes first is very good price if you are considering buying all the addons online. But and this is the main difference if you have played Fallout3 then you probably already had the addons so this is not good to you so for an old game (very good game though) is expensive.
Now in my opinion I would advice you to do something different.
But there was another way of getting the addons DLC very cheap.
If you buy the addon pack 1:

When this came out you could have traded it for £9
Same for the addon pack 2:

trade in value of £9 at CEX
Also the good thing about this addon pack is that you only need to install them once and that's it you do not need the cd after that (only the FALLOUT 3 cd)
So I bought the second expansion for £10 and traded it for £9 at CEX (£10 at gamestation) so in reality I got it for free.
Maybe this is why you are getting cold votes.
Good game thought but getting this version will not allow you to trade the addons for money.
I hope this helps.
