I too had the same issue. I've ordered cases from her in the past and got them promptly, then I pre-ordered a bunch of 2012 bowman sterling cases for around $1600 each and never received them. When I contacted her, she said she got the run around from her suppliers and couldn't deliver them. She ended up refunding my money so I guess I got lucky. I had a feeling it was too good of a price but figured if she was buying them wholesale she might just be making a quick small profit.
On a related note, I pre-ordered more 2012 Bowman sterling from ebay user: mrcardguy for $235 a box and never received them either despite all his glowing reviews. It is past the buyer protection time now, so I'm probably screwed on those. Anyone know anything about him? He seems to have stopped selling on ebay too.
