Thrifting to Resell

I love to thrift. But my body also loves to crap out on me and I lose energy quickly due to medical diagnosis. I know this is a me issue. And I am new to this community so my feelings my not align with others. If I am thrifting, it's for me. I live in a city with Goodwill Bins and I may have to start medicating myself and going there to hunt to negate resllers who find beautiful things just to jack up the price. I understand wanting costs to reflect time and effort into finding items. But idk. Reddit suggested to the resellers subreddit and I quickly realized it was not the subreddit for me. I just get frustrated when things are already difficult to find and it's frustrating. I think this is more of a vent because it's just frustrating to miss out on things. I remember going to goodwill in the early 00s and buying shirts for fun for like $1 each
