Dropshipping - how do I make sure I get paid first?

i had problems last time trying to dropship stuff on ebay but the customers did not understand that they had to pay first before i send item out.

how can i put that in my listing with out giving away that it is dropshipped?

I believe it is commonly known on ebay that you need to pay for the item and then it is shipped. You should not have to clarify this.

Yea. At ebay you have to pay before item shipped.

all people asking for the product before they pay are scammers....

You should never ship an item before it is payed for. Anyone asking you to ship an item before you recieve the money is scamming you .
