We have an a m a z o n seller account. we need a bot which can compare our price, to competitors selling price, and then change our price to match the lowest price. requirements: 1. we need to be able to select how often the robot runs. 2. we need a minimum field, so if we put the minimum price, it will never go below the minimum price. 3. the bot will need to read the price of the item and add it to the shipping to calculate the total price. The bot will need to change the price in seller control panel, which is SSL. the BOT will need to navigated to 4-6 pages to get the info it needs, it is straight forward. I will demo, the logic on Teamviewer, and also make screen shots to make it easy to understand. the bot will need to have an interface so we can add the items numbers of which items to manage, and then when the bot logs into the seller account it will find the items in the list, according to the items we have inputted in the admin of the bot. please download attached text file to see samples of the links, where the bot will have to be able to ready, and navigate.
