It's entirely possible they were never on the website: both Vit and I live near their retail store, and I (and probably he) bought them "the old fashioned way" (tm).
There were a few dozen on the shelf when I bought mine a few weeks ago. If that's all they had, they might not have bothered putting them online
I'm going to be in their neighborhood on Wednesday, and was planning to swing by and grab a couple more for myself. I'll pick up additional ones for people who email me before then with commitments to buy (my userid is "ran", and my ISP is "netgate.net". No HTML email, and no return addresses from freebies like hotmail or yahoo without prior arrangement: my spam filters are downright fascist).
Note that Vit said he paid $2.50, but he may have gotten them on sale: they were marked $2.95, so I paid $3.20 with tax. And I don't have a UPS account, so I'd have to pay regular postage rates. If you can email the store, and get them to sell them direct (even though they're not on the website), you might actually come out ahead.
If you want me to get you some, let me know whether you want the Rev B2 board (slightly larger, and easier to rework because there's more open space near the chip. Also includes a free BNC tee) or the B3 (smaller, lighter, might reduce the postage). I can strip off the box and docs to save postage, too: the board's in one of those vacuum-molded anti-static containers. If you don't have access to a DOS box, I can set up the board for you before I pack it, but let me know whether you're going to use it for 10Base2 or 10BaseT: the autodetect doesn't seem to work for me.
The rework turned out to be a lot trickier and riskier than I expected, and the DOS-based setup works, so I'm withdrawing the offer to do soldering for folks. The chassis rework to accommodate the BNC is easy: you just need to entend the cutout on the back panel by a few mm, and the board fits fine.
