Demand a refund, or partial credit. (go through their live Customer Service module and give them the image link to see what they have to say about it at least)
Even if you don't keep the box (which you should with these nice shiny ones ), the packaging is designed to be for display by collectors.
I could understand if they did it to a general release item, like say Metroplex, but even still, I'd be annoyed at not having the chance to have "keepable" or displayable packaging.
(not to mention, the chance of the single bit of tape breaking in transit and items inside come out and are lost)

I really hope mine doesn't arrive like that.
