The good thing was I noticed it. My worry is when I don’t.
I can usually find something cheaper on a different site (best buy, B&H, Microcenter, Newegg...although Newegg has been really bad for me lately, monoprice, Walmart). And the rare couple of times I don’t, I’m willing to pay the $1-$2 more (I’m much better off in the long run anyways).
Honestly, it’s really really hard to find something that is also available elsewhere, cheaper on Amazon than anywhere else for me. So I’m not willing to take the counterfeit risk, for basically no benefit.
