AH's at 20%

[Luke]

I like the equation, James! Good to know I'm not the only math nerd on here. Unfortunately I'm also lazy. I won something from an AH last night where I had just done a quick approximation in my head, and was surprised/annoyed when the actual number was $15 more than my guess. Probably not annoyed enough to actually do the math next time though

Math was my best subject in school, so I know how to do the exact calculation. But, I am also a lazy butt, so I just do an approximation in my head. But, I tend to wonder if other bidders remember the BP when the bid price of a card that I am interested in significantly exceeds what I think makes sense!

I almost never forget to factor in the BP, but I have forgotten to factor in the sales tax before on a couple of local auctions.
