> tell me is that good idea
The only good idea, is an idea that makes a profit !!
(at the very least, makes no loss)
and, unfortunately, you have provided no information on how your 'idea' makes money...
or the costs involved to produce and then recover those costs as 'sales' (to who ??)
therefore to what market you will supply and why they will choose you over someone else
(who may already be supplying...)
So.. back to basics..
can you do this idea without losing money
and can you sell at a price that lets SHOPs make a profit when they sell at a higher price to end users.. ??
