Hi fellow redditors! Thank you for taking time stopping by and reading my needing of help. It is kind of hard to explain without getting too messy, maybe someone with a little more knowledge could point me int he right direction. with that being said here is what I am facing. It is not a big dilemma or problem but would like to move forward with this. So, I am trying to learn how to do smart product inventory control. Meaning I would like to be able to come up with a grid or find a excellent iPhone and iPad app to be able to manage what I have and have it cross reference it with prices like what Amazon sell that specific item for. It doesn’t have to be only Amazon, i want it to be able to see what others are selling it for like Target, or Walmart, and so on. For example: Let’s say i take inventory control of 10 different shades of Lip Gloss and want to be able to see what Amazon is selling for. And be able to come up with a smart and efficient way of tracking, buying, and selling these things. ( not what I am buying or selling anyways... ) I am very very heavily interested in statistics, labeling what and were and at what price i buy. I know I can just go and manually do everything like make a UPC, smart link of where the item is sold and at what price, what I could offer it for and so on. I do not have a price gun or scanner or whatever they are called but planning on purchasing one soon. Willing to learn from all comments, good and bad. Thank you to all for who have spent a generous 5-10 minutes reading comments, post, and contributing your 0.02 cents.
