There’s a pizza slice place my wife really likes. She goes sometimes and she gets them and they’re $8 for a large slice (yes, sf prices); $10 with tips.
Every Sunday morning I get a Too Good To Go order and I get their last 2-3 slices for $5.97. I pick Sunday because they close early then, it’s easier for me to walk there, and there is frankly less competition on that day (they’re located at the ikea food court). It’s been a good mix of things, and it’s also the only pizza slice store my wife likes, so I’m happy to do it. But holy shit the price of buying anything is $$$$
