Application to integrate with Amazon Seller Central

We need an application to compare prices on Amazon against our own. It must be extremely fast and be able to find the relevant ASIN. It should then modify our price accordingly and upload using XML to Amazon every few minutes. ## Deliverables We have a database that contains our cost price for items. We would like to make sure our price is as competitive as possible through price checking. We envisage the final app being relatively simple, just checking and modifying prices then uploading them.
