Store Categories VS Blog Categories

Hi gang (Mostly Mark),
I’m a little confused…and was hoping to NOT have to hire on a developer for this matter…sigh.
I’m a blogger by nature, so I understand categories for a blog.
I also understand categories for a coupon code site.
BUT, there are 2 different category sections (one for coupons and one for blog).
This is a little confusing when I’m adding in categories for a blog section (and adding category to my menu bar) because it turns the blog posts in that category into a “coupon” so to speak.
https://christmasdealsandsteals.com (main site)
https://christmasdealsandsteals.com/blog/ (Blog section looks normal like it should…still needs some tweaks)
https://christmasdealsandsteals.com/category/black-friday-ads/ (category for this section looks like a coupon from this aspect)
The appearance of the 2 are much different, but leads to the same information. KWIM? So…is there something that should be done differently or am I SOL?
Thanks for your help!
