Amazon listing repricer - real time

I am an Amazon marketplace seller and we are in need of a Repricer for our products. We have a lot of products on our market so we cannot manually do it ourselves. We need a repricer to win the amazon buy box. On a listing, there are usually more than 10 sellers and the cheapest price wins the buy box. The buy box is the seller who gets the sale when you click 'add to cart'. The other sellers are on the 'NEW (36) from' list and usually will only get 1% of the sales since no-one will click and choose a more expensive seller. The buy box is constantly in rotation because nearly all sellers use repricing tools. However, most of these sellers have flawed repricers that take 5/10 minutes to update on the price listing. The problem is, that even if you update the price manually on the Amazon seller site, it takes 5/10 minutes to update. However, I need the price to somehow be updated instantly, even quicker than the Amazon site itself. There are currently sellers that have this sort of software. This means that they always have the buy box, even if others use repricing softwares, theres will update that same second and help them retain it while others take up to 10 minutes. What I require: - Repricing feature that beats the current buy box winner by £0.01p (with a min. price floor and ceiling) - Be able to increase back to ceiling price as soon as it hits the floor price (so other sellers follow and then its a cycle to the bottom again) E.g. if a product min is £10 and max is £14, I want the product to keep repricing against competitors and when it eventually reaches £10, it goes back to £14 and repeat. It's simple. - Change prices in REAL-TIME. They have to update INSTANTLY. - Different listings have to be able to adjust the minimum and max prices. - Interface which minimum and max values can be entered for products. Also names, descriptions and so on that correlate to the Amazon listing. If you think you can make this, lets talk!
