For those who work from home any advice how to go about this?

A few days ago I signed up to be an independent consultant for a work from home job selling candles and the company is pretty legit. I have been asked by customers to send a sample the problem is I'm not comfortable letting a bunch of strangers know my address and I don't think customers can order samples from the company's website. I would have to buy some but right now I won't be able to order some until Friday.
