I know why you did it. But "it's a dollar store," sounds far more reasonable than, "the customer is expected to know the value of everything in the store," which is what you're actually saying. You're making something seem obvious instead of saying that you expect the customer to look through the entire catalog to determine the average prices of goods and what was added when.

This was the first sale of brand new stock the guy was advertising. It was clearly the most expensive thing he sells. The buyer was a patreon supporter, they also clearly know the sellers catalogue.

And we're also not talking about a brick and mortar shop with a regular clientele, which is also something you added for extra feels. It's the same reason you gave them names. To project an image on it that differs from reality. We're talking about e-commerce open to hundreds of millions of customers. The scale is different and if a vendor wants to sell at such a scale, they need to be prepared for it.

The coupon was for patreon supporters, they’re also clearly are the modern day regular clientele.

If he wanted to be on a first name basis with his customers, he should sell in person to a local community. But he is not Jim selling to Bob. He's a representative of "ODGG, LLC" selling to the mass market. It is not reasonable to expect someone shopping on-line to know if a website is a 3 person company, 50 person company, or 100k person company.

He gave coupons to a local online community aka his patreon subscribers. They clearly knew who he was.
