How this store works - why stock keeps going down
When you purchase from this store you are effectively buying our time. If an item is listed as "in stock" this means the components for it are, in fact in stock but it is not put together yet. We don't prebuild items because what is popular at any given moment can vary wildly based on popularity of Internet videos, blogs etc and this will not change the fact that we can still only produce a certain amount per day. This may increase when we expand but we cannot expand until we are permanently settled - one of us being in the final year of college precludes this for the time being. We do not intend to be in this location next year.
Now the second problem is, online stores are not generally set up for this method of selling. You have to have actual items in stock. Because it's possible for us to build any item we offer, we therefore put them ALL in stock (components being temporarily unavailable may mean something stays sold out) and simply reduce all stock to zero when we are closing the ordering window.
This tends to work better than prebuilding items because it means that if you are around to buy, anything you want is available to you including very obscure items. Low sellers with longer production time like BNC cables might go out of stock for days or even weeks if we prebuilt them, because they don't take as high of a priority to restock.
Lots of people on etsy tend to sell their time and open themselves up to custom orders via buyer communication. We could do this but if we did it for every single cable, that would result in far more time in email communication which we'd have to tack on to the cost of cables to cover and more importantly: we would not be able to produce as many cables. Already we are working 10-12 hours daily.
Since we have moved to a one hour window instead of limiting sales amounts we can no longer list every week. Typically we will have an estimate as to when we are back in stock the same day we list, but will have to calculate when that date is after the window closes.
