Currently I can send the packages with the polish post mails only to the certain countries, see the information at the top of the page to check if your country is on the list. With the DHL I can send it everywhere except for Russia, for some other countries such as Belarus the additional fee is applied due to the, let's say, hard situation inside the country that makes the DHL's operations more difficult.

Feel free to place another order with the correct one, though please write in the message to the seller field to cancel your previous one.

Sure! Please write to sales@prox.com.pl with the title of [SWITCH SET REQUEST] and tell me what switches would you like to combine.

DHL of course as it takes just 2-3 days to be delivered but it's also quite expensive and outside of European Union it will be almost always eligible for customs taxes. It is safe to use just an uregistered mail if you live close to Poland. Much safer option is to choose the registered one. Also the farther away you live, the longer it will take for the postal services to deliver your package.

It depends on so many factors that nothing can be said for certain. That's why it's written that the processing times are only the estimations. I can get sick, I can get to the hospital, I can experience a mental breakdown especially that I suffer from depression, I can have some problems with getting the parts. A lot of things can happen that can make me unable to fulfill your order quickly. Keep that in mind.

It depends on which shipping method you've chosen and where do you live. The postal services in some countries are worse than the others which make any estimations incorrect. With the DHL it usually takes no more than 3 working days. With the Post it can vary from just few days to even over a dozen weeks,

If you've chosen the unregistered shipping method then there's no tracking available.

It depends. Some countries such as UK do not provide consistent tracking updates which can lead to no info for a few weeks. USA and Canada do not provide ANY tracking updates once the package leaves Poland. The last tracking status you'll see is "Sent from Poland".

Recently it almost never happens, however it still can. The post offices usually don't care about filling this info correctly. If you live in europe it'll probably show France or Germany, for NA it'll be United States and for Asia Japan or Korea. DON'T WORRY, IT'LL BE DELIVERED CORRECTLY AND THE INFORMATION ON THE TRACKING WILL BE CORRECTED ONCE THE PACKAGE HAS THE STATUS OF "SENT FROM POLAND".
