We've been trying to approach various 3rd party data feed aggregators to simply your data feed management process.
The first one we have is SellFire!
We've tried using their services as an affiliate and found that it is quite easy to setup and modify the product data settings. If you want to use our 1000+ product data but are not quite sure how to do it, check out SellFire and see if their services suit you.
Sign up a free account and give it a try. If you would like to take advantage of their paid subscription plan, SellFire provides our affiliates with a coupon code COMBOINK25 to get 25% off the price of your subscription.
Let us know if there are any questions. Hope this helps!
