Packie, RichFZS may have expected you'd do your own search of the forums regarding Busters. If you do so you'll find plenty of moans about slow delivery, wrong items sent or sent to the wrong place... though it's all anecdotal of course, they may be no worse than any other supplier.
However, they really gave themselves a bad name when people on here (well, the Yuku version) started experiencing fraudulent activity on their credit cards after making purchases from Busters. Rather than apologising and making statements to the effect that they were cooperating with police etc. they chose to get their solicitors to write a gagging order to the admins on the grounds of defamation.
