I'm not one to throw money at mystery boxes either, but after hearing so much positive feedback about comicalgems' boxes. I bought a couple from one of his sales. I was really dissapointed in the whole experience. The headliner comics were in the boxes, but we're beaters, and were third at best values in the boxes, which didn't even reach the $150 listing price.
Was also asked if I could choose personal payment so he wouldn't have to pay PayPal fees. I did. The most dissapointing thing about the whole thing was the packaging. The comics were not even boarded, or sandwiched in cardboard. They were squeezed into a plastic bag, and put in a shipper without any cushioning.
Lesson learned, and would not waste money on a Mystery box again.
