Sorry, I see it was not so clear.
Customers will stay somewhere also because they are attracted to the fact that sellers are “humans” not only shops. This is a practice I saw on Etsy managed by the makers themselves: They post on twitter, open pages on facebook (btw, thanks for the launch of my things on FB ) and so on. Create users interests, try to make them to become “friendly” and hopefully customers. It is also one of the reasons I write on electroschematics.com. People knows the creator of a product, can speak with him, ask about the product, ask for their doubts.
This is important IMHO especially on Tindie, where most of the sellers are makers, or creators or anyway involved in the production process of their own products.
The launch of this concept (hope now it is more clear) maybe interesting and attractive if the adhering sellers agree to use some discount bonuses, and these are noticed through the forum.
For example (but it is only an example): tomorrow the creator of the product XYZ is online: ask him all what you want and you will be answered, doubt solved, more examples and details got by his own “voice” (virtual). To all the participating customers for the next 10 days you can use a special discount of 10% on all the product line of the seller …
Something like this. How does it sounds ?
I make my products based on the cost + a certain percentage. My earning should be 10% but I put a 30% charge. Then create discounts. I think simply that as Tindie is NOT a distributor, why I should keep the money I save with this direct selling? Better many happy clients for low price high quality than the opposite.
Let me know.
