2018 Supreme court ruling affected how online vendors have to collect tax, even if they're selling to a state where they don't have a physical presence. I'm assuming there's a phase-in, or maybe an allowance for smaller mom-and-pop outfits, but ALF is a big time retailer.
Since everyone who lives in a state that has sales tax was supposed to be reporting their non-taxed online purchases to the state anyway, this makes it simpler, no? /s
