This looks perfect for some of my upcoming projects!

I just have a comment that the price of an individual "coffee" should be more obvious because it might not be clear before you look at the Buy button total (which is a bit low-contrast anyway).

At first glance, the 1-3-5 looks like the dollar amount you're donating, not a multiplier of a coffee cup since the coffee doesn't have the actual price anywhere.

Especially considering that a coffee price can differ from $3-$5 depending on each person's settings, I would go for clarity and either put the price in front of the coffee cup or use a coffee cup icon that has the price on it.

I'm super excited to try this out though! https://www.buymeacoffee.com/JessicaSzeto
