Problem is that the final cost depends on many factors. Not just first cost on manufacturing.
Also, prices can vary from month to month (even in toys).
For example, I can agree to a price... then said factory gets an order for 100,000 units from another customer. They then have to change prices moving forward to justify working with our small numbers.
Oh and of course, a project like this will be run like a business, not a charity. With that said, having somekind of contributtion to AROS rom replacement bounty makes total sense.
In the end you can't please everyone. Having done toy projects it's funny to see folks complain about retail prices at release.
They then refuse to purchase said item at full retail price. They hem and haw on message boards, write you letters.Call your office.
They wait until the item goes on closeout. Then drive 20 miles to every mass retailer to pickup mutiple copies of the once $30 item for just $9.99.
They keep one or two and resell the other 10 on ebay at a premium.
They're even bold enough to post on your website and offer the items to mesage board members... at a premium price of course. LOL!
Meanwhile the toy manufaturer takes a $100,000+ bath on a markdwon penalty from retailers.
No thanks!
Having a specialty product at a Hobbyist price avoids such a mess.
