Based on what you wrote which is quite plausible, I checked the local prices and the dealers and the prices go from CHF 49 (~US$ 51) up to ~CHF 86 (~US$ 89) and none of the dealers who normally go for such agreements is listed. Now, I am guessing but seeing such a variation sort of points to the absence of such an agreement.
But I thank you because you pointed me towards the background and the reason of the price difference. Parallels did a 1:1 conversion from $ to Euro (so the $ 49.99 was "converted" to € 49.99). In reality, US$ 1 = ~€ 0.75 (as of Today) so with each sale to Europe Parallels makes 25% more money than with an eqv. sale in the US. Switzerland has its own currency and is not part of the EU but we get the € to CHF conversion and not the US$ to CHF one. Last I looked Parallels was still a US company so this conversion table looks more than a little suspect to me as it lists $1 = € 1 = CHF 1.23 which is MUCH better than $ 1 = CHF 0.92 (Todays rate).
The trend these days in my experience at least, is towards having unified prices and not making such a mess out of it. In my company, we are selling software services to international customers too and we either charge in CHF or the local currency at the date the invoice was written but we prefer CHF.
