There are most certainly bootleg digipaks. Also, the low-cost pressings out of Eastern Europe and South America (the subsidized releases that are NOT supposed to be sold out of territory) frequently come in cheap, flimsy digipaks.
I did not know about bootleg digipaks, seems like a lot of trouble when normal boots are so much easier...as for Eastern Europe and S.A. releases, I do not have a problem with them but to each their own I guess...if paying extra for official Western Europe releases works for you then so be it...
