Yea you can call it whatever you want to, but that won't mean they actually dropped the prices. $1 is nothing anyway, I'm pretty sure they used to be even a little cheaper than what they are now in USD.
No. See, I understand that you'd think it's costing you less, but it's really not. If it is the exchange rate (which actually makes sense, because although the dollar had been falling against the euro in the last year, it has gained fairly consistently since the beginning of April), then your dollar is literally worth more than it was when the price was a 1$ higher. So you are paying less dollars, but it is equally as expensive.
The exchange rate is a tricky thing, especially when you use one of the currencies now, but in the future will be using the other.
I just know that the US dollar going up in value = good.
