Amazon are recommended IF you are NOT a MIB collector.

They are really cheap for a reason, and if you are wanting to save money, use them.
But, if you are wanting mint packaging, go for an more expensive option (like BBTS or local stores).

(I think if they were forced to spend more time on the pack of the boxes and provide more packing material, they'll start charging more the for extra labour and resources... and then they won't be any good - which is why I've never hassled them about it, and always recommended them ONLY IF you don't care about the packaging... and not purchase books with toys)
