I hear over and over that you should validate your product before buying in bulk.
The problem is that I have designed a custom fashion product. The manufacturer will only ship 100 per style at a time. I have a few samples but not enough to truly validate.
Also, in my opinion, you can't validate a fashion product by selling a few samples on ebay, particularly if they are high end.
I know similar products are in demand and I know my market. Is this enough to gamble bulk buying?
