Pretty sure if I buy a Spigen case on Amazon fro the Note 7 it will fit just like a Note 7 case in store will lol. Sorry we can just agree to disagree since this is getting ridiculous at this point. I don't get how a case sold BY the maker on Amazon isn't quality like a carrier store. That makes zero sense.
There are certainly different levels of quality. My personal experience with spigen, ringke, Caseology, and vrs is that they are good cases but that they aren't on the same level as otterbox and tech21(either in quality or in quality control nor in price). These cases are set well below what Verizon sells cases at, at a slight reduction in quality. Of course Verizon doesn't sell spigen, ringke, Caseology or vrs either.
Personally, I bought the Spigen case for my note 4 and while it did fit, the mic hole at the bottom was completely blocked. Went out and bought a case from my Verizon store and it had the mic hole properly opened.
I also had a spigen case on my note 3 I believe that cracked when removing the case. They did send me a replacement case, also cracked in the exact same spot. Others on here and amazon also experienced the same problem.
Also I had a spigen nexus 6 case, it had multiple marks on the case, clearly not new despite being sold as such.
I bought a Caseology case can't remember which phone... It didn't fit well at all.
Probably other issues that I can't remember now. But then compared to cases that I bought at Verizon, my Verizon cases seemed to work better and of better quality.
However back to the topic at hand, for the identical case on both sites, I would have no problems buying from whoever was cheaper. But personally...if I wanted a guaranteed fitment and quality, I would go with Verizon. I realize going with spigen cases not sold by carriers, that there is a risk.
Now when talking about $15-20 vs $35-45 for carrier stuff (less my 25% discount then I prefer to go carrier. Now if you are talking about sale prices in the $1-3 price range then I have no problems going with spigen /vrs /ringke, etc.
