Opinion - Merch Drops - Buying to Sell to Other Swifties

I’ve been thinking about this since the LLFP drop where I was thankfully able to purchase one for both myself & my sister-in-law.

What’s the general opinion on buying solely to sell to other swifties at cost + shipping? I’ve never done this - and would never do it to profit because resellers are the reason I never got to go to The Eras Tours - but hearing everyone’s struggles to get them - would it be frowned upon to try to get a couple of in-demand items occasionally to help other Swifties out?

I work from home so generally I’m around when something drops.

Again - I’ve never done this before but it’s been eating at me since last week that maybe there’s even a small part I could potentially do to help other Swifties out.

Thoughts?
