How much does Botox usually cost?!!

I'm seriously considering getting Botox these days, but the prices vary so widely that I don't know what's right for me. Some places advertise super cheap prices as part of promotions, while others charge several times more for the same area. I really have no idea what a reasonable price is.

I am particularly considering getting Botox for my glabella and jaw. I am self-conscious about my glabella because I am often told that I look like I'm frowning, and as for my jaw, I feel like my jaw muscles are developed due to my habit of clenching my teeth, which makes my face look bigger lol. So I am looking into Botox, but I keep hesitating because of the price.

I heard that there are domestic and imported Botox products, and since I heard there is a significant price difference, it’s making me even more confused. I feel uneasy about the really cheap ones, but the really expensive places are a burden... Since it’s my first time, I’m being extra cautious.

For those of you who have actually gotten Botox, please let me know how much it cost!! I'm also curious about Botox experiences where you were satisfied with the value for money.
