Here's how you calculate the total spent on the shirt so far: https://en.wikipedia.org/wiki/Arithmetic_progression#Sum

16,836€ (183 sold)

Weren't 182 t-shirts sold? That would put the total amount made to 16,653.

But yes, that's the way to calculate it.

I think you're right. A price of 183 means that the seller is offering it to potential buyers at 183, not that it has sold at 183. So your calculation is correct.

Yeah my bad, 183 t-shirts were sold but your total is still correct because the first one was sold for 0.

EDIT: Someone bought another one, so my initial total is now correct lol

Did it start at 1€?

At €0 according to that page. He kept that one himself (so 183 shirts have been distributed, of which 182 were bought). Shirt 0183 is the 184th shirt.

> First shirt was embroidered on 25 February 2024 with the price of 0 euro for Dries.
