Pay me to buy your stuff
A brand-new microwave can be pretty expensive, which is why you should try searching on the internet for a second-hand microwave. But here’s the thing about buying stuff from strangers online. Unless they offer to deliver, it’s your job pick the item up or have it delivered to your home.
The audacity of this person to ask for gas money to pick up the item for sale is just astounding. Did they take some time out to think about what they were typing before hitting send? The seller’s reaction is on point. There’s no way to respond to such ridiculousness.
