I decided to do these caps a little differently. Instead of having them go immediately after I put them up, consider this a notice of when the sale begins.
At 14:00:00 forum time (12PM PST) 1/25 orders open. Just respond in this thread and the first one to do so at 14:00:00 or later gets the cap. I will contact you via PM to get your Paypal address, then send you an invoice. Like always, I'm open to trades, but there's no guarantee I'll take the trade offer. Shipping can be combined for a small price reduction for multiple caps except for caps that are Geekhack donation caps. Geekhack donation caps require me to confirm that you won first and require mod confirmation before the cap will be sent.
For Nebula caps, priority will be given to someone who wants to buy the matched set. If someone does not take the matched set in the minute following the first single cap order from the set, it will be split into separate parts.

Visitor Caps and matched color HKW, Cycap, and Trooper Cap
Color name from Left to Right, Top to Bottom:
Skeletor, Miami,
Visitor (the first one made), El Diablo, Pluot, and Sic 'Em.
The colors are slightly off in the picture for Sic 'Em and Visitor. Visitor is grey without a greenish hue in the main body and Sic 'Em is a darker green than it appears in the picture.
Skeletor has been sold already as part of a pre-release early sale for answering some trivia correctly about the colors.
$15 each, Pluot is $15 donation to Geekhack

Matched Hard Knock Waz: Pure White, Alien Green, Miami Magenta
$15 for Alien Green, $10 if bought with the matching Visitor cap. Pure White is $12 since I had to do some post work to make the stem tighter. Miami Magenta is $10 since I'm working on making the stem tighter, but it may be loose and need to be tightened with tape or something at the time of sale.

Hell Red Cycap and
Goldenrod Trooper. $15 Donation to Geekhack each.
If you buy the Goldenrod Trooper with another cap and can correctly tell me why I chose that name, I'll knock $3 off the other cap's price.
And thanks to everyone who supports my experiments. It allows me to keep experimenting in different areas (like my metal casting) and helps me afford to keep experimenting with different non-traditional dye coloring materials.
Edit: I forgot to say these are US shipped prices. International will cost a little more since shipping is triple what it costs within the US.
Edit 2: Alright, here's what I have. Please correct me if I'm wrong.
