That's not what the timer is referring to. The 15 minute timer is in place due to the exchange rate. Newegg prices their items in dollars, BitPay converts it to a BTC price and presents that price to the user. They can't show that same BTC price forever, becasue if the price of bitcoin drops by 50% over 24 hours, and you decide to leave your window open and order then instead of now, you will get whatever you are buy…
If it's a moving spot price that lasts just 15 minutes, is the exchange market deep enough to keep people from abusing this? By placing a huge number of buy orders at a time when the market is quite shallow, all within a few minutes (temporarily driving the exchange price up sharply) the BTC-denominated price of goods on Newegg can become very low in a 15-minute windows. Huge numbers of orders ($millions) could then…
Ex. The Bitcoin is on an uptrend and went up 30$ in the window between when I checked it ~8 hours ago and just now. Even if it managed to do that in a 15-minute window of time, that's only 30-dollars off of every 600 dollars you spend. A 100$ dollar order will only see a 5 dollar 'discount'. And if it goes the other way, they make a bit more, so over time I'm guessing it'll mostly even out, Maybe a bit more in the consumers favor if we assume the BTC price will end-up going up.
