What are some free sources of large scale data that can be collected online in relation to e-commerce?[reddit]/r/datasets
As the title suggests, what are some sources of large scale data collection that can be utilised for the purpose of gaining insights to help drive decisions related to e-commerce?
I am putting together a university project which broadly aims to do the above for commercial gain, using machine learning algorithms, something I am very new to but which is a requirement of the project.
Recently looked into collecting data from Amazon to 'train' the software to provide insights that could be use to optimise listings etc, but have realised that the data collected using the Amazon Product Data API is restricted, and to scrape (another new topic for me) is naughty and against ToS, not a good start when suggesting a project to the project coordinator, therefore I am wondering what other similar sources are there online which is either not restricted, or much easier to gain access to on a large scale?
Any general advice is also very much appreciated as I am learning as much as I can in this early stage.
