I have a list of 500 products that I need the UPC and Amazon ASIN. I am looking to buy research services for $0.25 per UPC you find and $0.25 per ASIN you find. I will email a spreadsheet with a list of products, manufacturer part numbers and the manufacturers. The ASIN is simple, find the product on Amazon, scroll down to the ASIN number, copy it and paste to the spreadsheet. Many times the UPC will be on the same page. To find the 10 digit UPC, you may need to search with google. For many products, you will not be able to find a ASIN or UPC. It's a pretty simple process, but time consuming with a lot of clicking around. Please PM if interested.
