[GeneralQuestions] USD -> BTC: Fluctuation Padding

When transferring some USD into that coinage we all know and love, most prefer to put a couple dollars extra into the bank for security if the prices change. I have a question about this (my intuition is saying this belongs on /noobs, but, it'll largely go unanswered)...

Say the price is 0.54BTC - and it doesn't change a bit. Couldn't I just bust over .54BTC no matter the exchange rate, and be able to purchase the listing?

...Maybe someone can walk me through this logically. I don't think the math is adding up.

Prices are set in USD.

You will almost always end up with less BTC then you start with.

If the price of the listing is set in BTC, then yes. More commonly, however, prices are pegged to USD and the BTC price of the listing fluctuates up and down depending on the current value of the coin. Also be aware of network transaction fees. If you don't take those into account, you're gonna come up a few thousand satoshi short for your purchase.
