I think he stopped selling it like the "bulk repair lots".
BTW: I don't recommend buying many raw jacks anymore, most laptop dc jacks are either harness/wire based or on small power boards.
I carry a couple hundred different jacks. Loose, harness, power board and I would say that 75% of the jacks on dcpowerjacks are no longer needed.
Many harness jacks today are priced the same as raw jacks, so it makes little sense to do all the extra work. Even power board jacks like the 1525 Inspiron can be had for $5, 1545 for $10. Almost all of the G and CQ HP series harness jacks go for under $10 and who wants to rework 6-8 wires ?
We do see a huge number of Asus machines A/X/K 50 series coming in with broken positive pins (pj033 on dcpowerjacks) or common acer/gateway (pj038), some older dell (pj014), but compared to a few years ago you don't do as much soldering when it comes to jacks anymore.
HP and Dell love to make exact length cables and glues the hell of out of them so you can't rework most without ruining the harness. Sony and Toshibas are easy to rework, but there is only so many you need once you learn about cable lengths and plugs to the motherboard, it makes it not worth reworking even a 4 wire jack.
I think its best to buy two everytime you need one, unless its expensive. If you see a steady flow of one type coming in then buy 5.
One day I might come up with a list, but its too much work right now.
