hi everyone. recently, i have found a wholesale company online in FL. I think they focus on export. It seems to be a large company. I want to buy a lot of stuff from them. However, I can't find their website anywhere but I do see their information on many international websites such as name address and phone number. How can I make sure they are a legitimate company? they are selling a large quantity of the stuff I want now, and I have very little time to consider. I don't think I have time to go there right now. they request to pay all before they prepare the shipping. Can someone give me some advice? thank you so much!
