This type of plain white cover with some text is usually reserved for restricted (adult) magazines. Some bright spark decided this was the best way to communicate that the pack contains the current and a past issue of PC Advisor.
I suspect that the editorial folks will not be happy when they see their cover has been covered up.
Customers are not happy at the cover-up and I suspect that will probably be reflected in sales this month.
Curiosity killed the cat they say.
I have sold out! More are on the way, the only thing I can put it down to is good old fashioned curiosity, it certainly is different.
I suspect though that this will be a one off as the customer will be dissappointed, I think, in the product inside.
