I definitely understand the concerns. But this is an issue with a number of online retailers, isn't it? If it isn't Amazon, it's Hasbro Toy Shop, Target, WalMart, TRU.com, etc. The only online stores that you can count on for good packing are small businesses that deal almost exclusively with collectors like EE, BBTS or Brians Toys.
Not really because with Target, WalMart and TRU I can also find their exclusives in stores, so I may not find the quantities I need, but I typically find my MIB one at the physical store and then supplement with online purchases my opener set.
Hasbro Toy Shop did make an effort in the last two years to try to ensure that the SDCC exclusives arrived in great shape. My Carbon Freeze chamber set was extremely well packaged.
And just recently, when I ordered Class I vehicles from TRU.com, they arrived well packaged and all in good shape.
The one place where NOTHING ever comes in good shape? Amazon.
Up until now, all I have ordered from them is stuff I'm going to open, so it's no big deal. With the Slave I and TIE Interceptor, I'm going to want one of each MIB so it is a big deal, hence my concern.
