AFFILIATE DISCLAIMER:
Everything I link on my website is to help you and provide you with the information in the fastest and easiest possible way. Links to Amazon will usually be affiliate links where I may make a few cents when you make a purchase, and ONLY if you make a purchase.
That being said, sometimes there are better deals on sites like B&H Photo or Adorama for Photography specific items. If that is the case, the Amazon link is there just to show you the option and get some info, but you'll see a disclaimer next to it that B&H or Adorama (or even your local camera shop) will be the best option for purchasing in bulk.
Please note, I do not post links to items randomly. I either have them in my classroom, use them in my own business or trust the brand I'm promoting.
