I think if someone ask you for a catalouge with the prices and you will do it, that means you are sincere of your business because you cannot expect everybody will buy the product even if you provided catalouge. Another thing is, if you don't want to give what the customer want when they are not ordering you something, you can do that later when they already order you even 1 item and go from there.

I have an experience as a buyer and I don't know yet if I will receive my item or not because they seller doesn't talk to me anymore after I paid the money just last Wednesday but I am still giving them 2 weeks and then i will post that they are fraud and fake company even if they put all their information in ECVV. I ask them a catalouge with the price to send it to me when they send my order. I think that is fair enough for the seller and the buyer.
