GBP to PLN: Best way to get good exchange rate? [22]
Go to the HSBC bank here in the UK. They offer emigration/re-immigration services for people just like yourself. They have a branch in Warsaw and money can be drawn from cash points.
Get to know the cash points you are going to use. Some cash points will just refuse your card, not being able to recognise it, some charge a fee while some don't. HSBC advertise this service on TV. I have used them for this facility for a number of years, not just in Poland. They have the largest number of branches in the whole world. I know they have a branch in Warsaw, I've used it myself. Enquire whether they have any branches in Poland outside Warsaw. My experience of kantors is not very good and I shy away from them and I go back to to the days when there existed 'mobile' kantors, floating about hotel entrances and made a 'pssst-pssst' sound as you entered or left the premises.
The advice given by terri is very, very sound; please heed it, though don't be alarmed by it and don't carry the plastic bag in your pocket and take it out just for the purpose of putting the money into it next to the cash point. Take it out well away from the cash point and put something into it first, then approach the cash point. Remember, also, muggers were not born yesterday and are aware of these little tricks.
