There is a qualitative and quantitative difference between someone who runs a literal garage sale once a year to clear stuff out and someone who is running a garage sale every day, 365 days a year, buying product for the sole purpose of reselling it at their permanent garage sale. Local regulation usually places a fairly arbitrary but still useful benchmark of 4 garage sales a year before you need a business license. At 4 per year and a max of 1 day per garage sale chances are you're not making tons of money. When my family would run their garage sales back in the day a hundred dollars would be a big day. It was more about clearing stuff out than trying to make money. This is placing a fairly arbitrary but still useful benchmark of 200 sales or $5,000 in revenue in a year to be considered using this as a business. If you sell 200 distinct items I'll buy that it's a business. If you're selling $5,000 of merchandise, I'll buy that it's a business (or you're selling a used car or something of similarly high value). Either way you're a business and need to start abiding by business regulations, including things like having a known address.
