relaxthere is no law about what you say to suppliers of goods on the internet.
The only time you need to worry that you are not a wholesaler is if the company that your buying the item(s) from asks for your resale license in order to take the sales tax off. Even then is not mandatory - but having one will make things cheaper. A resale license is used by businesses who collect sales tax and send it to their state sales tax fund. Keep on buying, as long as you have the money. You have not broken any rules or laws.
