Sometimes it makes me feel like a crazy person - I bought some new headphones a few months ago, and walked to a physical Best Buy store to make the purchase, because I had no confidence any online retailer wasn't going to sell me counterfeits, and the manufacturer was selling at full MSRP instead of the slightly-cheaper usual going rate for them.
And for what its worth, the store experience was totally fine. I'll give them my money again next time I need something tech related.
