CVS extrabucks question

So I was watching this creator on TikTok @couponing4beginners and she had a video up where she saved a bunch of money buying toothpaste and lotion. For the toothpaste, she received $10 extrabucks for spending $20 on Colgate. Her total was originally $21.97 but it got lowered down to 10.97 after she applied her coupons. How was she able to get the $10 extrabucks after the purchase if she only spend $10.97 after applying coupons. I’m trying the same with an online order and it doesn’t qualify me for extrabucks unless I actually pay $20.
