Working on a price-matching bot and have a few questions & would appreciate any feedback

Hi r/Couponing,

So I am wondering a few things about the habits of those who coupon, and was hoping you could provide me with a little help.

Outside of coupon-ing, does anyone even care about price-matching? If so, do you pricematch while in store? Or is the shopping/pricematching pre-planned? Do you use any apps/websites to help with this? If the store doesn't pricematch, does that influence your decisions on shopping at that store? If there was a facebook bot where you could send it barcode photos, and it returns cheapest prices, would you use it? Any thoughts or feedback would be really helpful, and greatly appreciated. Thanks, BrokeDesigner0
