It isn't true. It is whinging.If it's true that HUKD only allows links to vendors where they get some kind of referral bonus, then eventually any competitor would probably end up the same.
Money talks.
It started off as a gem of a site for people to get bargains, but clearly it's just another business now making money from affiliates and sponsors.
Mostly likely that's why deals posted by @Lmg80 and @Marky got deleted. It's got to be Amazon or Currys or someone with a referral scheme in operation.
