Well since you asked tossing out my long winded thoughts from following along batch 7's journey.
Enjoyed seeing the first off the lil buds 2.0 come to life.
Feels like the start something big with the design now set and more option's like all the mix and match options becoming available. Will there be options in the future to buy the backplate in a different wood that would fit batch 7 and beyond?
The switch box doesn't look user changeable. But I could see buying another contrasting backplate.
Another thing I like that you are posting pictures of unclaimed units. Feel visual is a great selling tools.
Have a ideal on items like your DD cosmetic damage one of a kind items. The things not offered in a normal batch. Is to hold off selling them till a batch is ready to ship.
Say your shipping Monday. Midnight the Friday before you post pictures of items and what you feel a fair price for sale here. The excitement would have built all month. Would allow a easier method since your only answering fielding question that weekend about these items.
People would understand these items are priced higher since going out right away and one of a kinds.
Would also bring people to the thread to check out when the next listing will be. Even if they don't buy a special unit. There more likely to buy one in the next batch. Since there here reading checking out latest pictures and info.
You wouldn't need to be spending time answering fielding question as these unit as they become available. Could all be done over the weekend before shipping. Also less likely of misunderstanding of when these unit will ship.
Could also bring people by the site to order addition item. Maybe have a noon Saturday cutoff on stock items to be shipped with Mondays batch. Then you wouldn't need worry then about extra postal runs on small item.
With the wait time on these unit I like the batch shipping method you currently use. Feel it is the fairest way to ship. If you started shipping as you finished or what stock etc would only lead to misunderstanding hurt feelings.
I think you could tie the 2 ideals together. Most people would understand that shipping by batch is just the easiest fairest way for you to ship. This way the batch orders and shipping stock items is done just one time. Allowing you more shop time.
I'll much rather see you making these than spending time figuring out who what when why on muti shipping times orders and options. Or endless running back and forth to the post office.
Sorry ramble on but you did ask
