Interest check was here
Hey guys, I've gotten a ton of responses on this. We can get at least 50 orders at the 50-unit ($4.28 per set) price, so I think that this can be graduated to group-buy stage.

So, if you want one set of bumpy goodness in the CONUS, it should be a little over $7 shipped CONUS! (I estimate around $7.50)

To recap, this is a set of F and J keys that fit with DSA Granite, but have homing bumps instead of scoops/deep-dishes.
For the uninitiated, homing bumps are a raised plastic dot on the center of a key. Similar to the bars on most keycaps, but on DSA, you can't get bars, you can only get a dot. As an example, the bottom board here has a homing bump on its F key (which has a "5" legend)

How much is shipping?
[*] This is the biggest complaint people had about the Interest Check. So I've decided not to ship via Flat Rate. Instead, I'll be doing First Class + bubble mailers. This should cost <$3 for CONUS and <$4 international.
[*] Note that if you want insurance, you'll have to pay for that yourself, and I won't be responsible for uninsured packages being lost in the mail. This Group Buy is being run totally at-cost! There's an option for insured vs uninsured in the GB form.
How long will this Group Buy be open?
[*] Once we reach 50 units, I'll make another, last-call post about this, and give it about another week, and then place the order with the number of units we have.
Will there be extras?
[*] Maybe a few. But they won't be made available to anyone until I have confirmed that everyone who was in the Group Buy received theirs successfully, because otherwise they get first dibs on the extras. Then maybe I'll have a few sets left over to sell. But don't count on this because if you don't join the Group Buy, we might not reach the MOQ of 50 units!

Are there any possible further price breaks?
[*] Yes! Here are the volume discounts Signature Plastics quoted:
| Sets ordered | Price per set |
|------------|---------------|
| 50 | $4.28 |
| 75 | $3.40 |
| 100 | $2.96 |
| 150 | $2.68 |
| 250 | $2.16 |
| 500 | $1.90 |
If we could hit 75 units, that'd be fantastic. Everyone would save almost $1. And I think that it's feasible!

I'm more active on Reddit than anywhere else, and I have a bunch of confirmed trades on /r/mechmarket, so I'm hoping people trust me.

Here's the Reddit thread, which is my main "home-base" for this. Feel free to PM me here, on GeekHack, or on Reddit, but I will respond MUCH faster on Reddit.
Thank you all for your interest. I hope we hit the 50 units right away!
