I have found that I can get BCW supplies a lot cheaper on Amazon then on the actually BCW site. I have 2 of the 1600 count boxes and 2 of the 3200 count boxes. I really like these and need a few more. I did have to order a few extra packs of dividers since they only come with 4 (3200) and 2 (1600). I have almost got my autographs/sketch/relic/printing plate collection organized in these.
I have one 1600 count to my son and he gave me the two dividers because without them his entire Harry Potter auto/costume/prop/motion card collection barely made into it but they are all in one box now.
