I found a phone that is 1000zl in Saturn for 700zl at one of those small shops. How can it be so much cheaper? Does anyone have any experience buying from them?
Far lower overhead, lower profit margins, more creativity with regard to supply (not illegal supply but the owners will do things like buying a car boot-load of phones in UK/France/Spain and then driving them back to Poland).
Saturn tends to be more expensive than other suppliers for pretty much everything. A good alternative is ceneo.pl It's a price comparison site for online shops and you can usually save at least 20% on Saturn prices, usually more.
