Is it not obvious? Indiegogo, Kickstarter et al are designed for funding startup projects. Project in a concept stage. Projects that may or may not see the light of the day. Dreams.

If you have a finished product, you do not sell it on IGG. You sell it in a shop. Yours or someone else's (Tesco, Wallmart, Amazon, eBay...).

Likewise if you want a finished product, you go to a shop.

If you expect a finished product from IGG, you are a fool.
