I did some research on the prices of the company what you sent me in your earlier post. This is what I found out. There is a trader on a local auction website who sells 'printed' return address labels for about HALF the price of the 'blank' return address labels that this company is selling! I need to find a company which sells real cheap in order for me to resell them at a competitive price.
Thank you for your continued help. Looking forward to the outcome of your research.
