Ok, perhaps I should point out here that my job description as Community Manager is to assist members WHERE I am able, hence me not replying earlier....however your thanks for me at least trying to assist at this point is GREATLY appreciated!
As for me not knowing your business model, you're absolutely correct, in fact you original post, and your follow whine gave absolutely no indication that you were looking at drop shipping as the resource.
What, everyone is just expected to know what you want?
I suggested shipping maybe an issue because I had assumed, from the dramatic lack of relevant information, that you were looking at buying in stock, not some drop shipping platform!
You don't care where the products come from, as long as they are from USA or Canada....interesting little disclaimer, you see I would consider that to mean that you do care where they come from, but that's just me!
You want members to assist you, I would suggest that you don't cop an attitude with them as well or they will also steer well clear of offering any advice in the future.
Good Luck, I'm getting the feeling you may well need it...but that's just me!
