Not just you though, I noticed a few people seem to come off that way. I don't know about the other person but for me some people seem a bit surprised or think it's ridiculous because I spent that much on cards. But I didn't actually buy any packs, I chose to buy opened cards being sold as separates or in bundles {which is actually cheaper than buying sets of the packs so I don't get why people who spent so much didn't just do that}. And what I worked out, the amount of cards I got from bundles that didn't have duplicates is the same amount it would have cost per card, just 10 dollars more in total.
But I did that because after seeing how many packs people were buying, I'd rather just spend the money and get the cards I wanted. In general I don't like seeing people being or come off as rude based on how much someone has spent, but I can totally see why anyone would be concerned
