I’ve never thought much about it, always consider it’s just a percentage. I am in Canada but it’s pretty much the same. Googling “tipping buy one get one” turns up this snippet from a Quora answer:

> The amount of effort the server devotes to your ordre is the same regardless of what the owner charges for your meal. So tip on the original, undiscounted price. And tip at least 20 percent.

Kind of funny, when it results in a higher tip I should consider the amount of effort.

I expect if I said I was only tipping $2 on a $100 bottle of wine at a restaurant because it isn’t any extra effort to grab an expensive bottle the poster might not agree.
