Tbh im glad you said something cos I when I went to grab a source I noticed the possible fees coming up. Still worth it in my opinion and Eth becoming PoS is the reason I decided to also use OpenSea even with the lazy minting, PoW is gonna get pushed out the way soon enough (not 100% just compared to PoS). I should add "NO GAS FEES!" like I see others do when selling NFTs on Polygon. I am sure many others are thinking the same as you. I wouldn't buy an NFT with gas fees like that either. Not unless I was rich enough to not give a damn or investing in a high end NFT. If I paid $109 gas fee on a $20K NFT I probably wont care lol.
