Is NOBODY wrong in the post ? POST : I feel like this issue is one of the least significant posts on here, with problems relating to family, life, death, career floating around, I almost feel embarrassed having to ask this, but this is a rare instance where I really cannot make up my mind whether or not I did wrong. Help me, reddit.

So for more background information, I entered into a draw on a website. The draw will happen on April 5th which has not happened yet at the moment of posting. Their rules are that if you win, they will charge you after you win, and if you don't get what you want, they charge you nothing. No transaction occurs.

As you go through the buying process, it makes you check a box, and I quote: 

&gt;I understand that if I win the draw, the product will be dispatched and I will automatically be charged the price of the product plus shipping. I also understand that once my card is charged I cannot cancel the order or return this product as ALL SALES ARE FINAL.

I entered the draw, and decided to back out yesterday, April 2nd. I emailed them insisting to withdraw me from the draw, but they insisted that all sales are final and that they cannot do it because "the inventory has been locked in" or something like that, I didn't quote exactly what they said. I know for fact that my card has not been charged like the box checked, and I get that all sales are final, but this sale hasn't even gone through??

From my point of view, it's almost as if I had something in the cart, ready to order. And they have my credit card information. When I remove the item from they cart, they won't let me do it and say that I must purchase because it's already in my cart, and I think that's stupid.

From their point of view, maybe I really am just an irate patron that didn't spend enough time reading the fine print (even though I did) and asking of a great inconvenience of them to remove the order and complicate their drawing process. If someone has worked in a similar environment, I would really be keen to hear about your experiences as well. Is it really that big of a deal? Am I overreacting to making a decision too rashly that  I should really just own up to?
