There is a massive difference over not paying extornionate fee's, and not paying a few hundred thousand more on a deal which is already much cheaper than we'd have first thought anyway.
Buying someone like Long for 8m is reckless, paying a couple of hundred k more for Foster is sensible. Goalkeeper is the most important position we will buy for this season, given the fact his deal is apparently much cheaper than anyone could ever have thought, paying a tiny bit extra isn't going to bankrupt anyone.
