I'm trying to find a deal on a Graco car seat for my cousins baby shower in three weeks but I'm super stressed about the price. I saw it was on rollback yesterday but then it went back up and I literally have no idea how people keep track of this stuff without staring at their phone all day. Sorry if this is a really basic question but are there like actual apps that tell you when the price drops? I was thinking maybe I should just check the website every hour or something but that seems crazy. My logic was that there has to be a better way but I'm totally lost on where to even look or what to download... does anything actually work for Walmart??
