Since the very beginning of accepting EUR payments in 2002 I often see there is the same EUR price value as original USD price.
Many international suppliers, stores, e-shops offer the same stuff in US and Europe. Price tags are exactly the same, but currencies are different.
For instance, there is a stuff selling for $59.99USD in the US but it will be at €59.99EUR in EU.
But in the UK the price will be always correct, say (59.99/1.6)=£37.49GBP.
This usually happens with international stores located and registered independently in the US, UK and EU.
So, why $59.99USD = €59.99EUR for EU, but £37.49GBP corresponds the exchange rate in the UK?!
This usually doesn't work with on demand currency conversion option where available on websites, because the actual billing currency is the only one based on actual e-shop location (UK — GBP, US — USD). The currency conversion looks just as a helper option in this case, these are not real billing prices.
