We've added an optional additional column to our daily data downloads (aka Price Guides) to help you better link our data with yours. The new column provides a unique identifier for each product in our database. Before this change, you had to link our data to yours by comparing the UPCs or product names. The programming for that technique was more complicated than it needed to be. Now, you can simply correlate our product identifiers with your own product IDs to easily and consistently update your database from the daily downloads.
If you already have your system configured to use the older file format, don't worry. The old format is still available at the same URL you've been using and you don't need to make any changes. If you do want the new column, replace
today.csv in your Price Guide URL with
