Hi.
Under the following heading, you can read a bit about shopping in Poland:

I will probably go down to Poland myself on 23/7 and return 25/7 with a large truck and will likely have some space left over. If you're interested in some pallet spots at a good price, just let me know.
What I will be shopping for our house renovation is: Appliances = 20-30% cheaper on most things + for example, Whirlpool has a world warranty. Tiles and ceramics = 30-70% cheaper. Wooden floors = 20-30% cheaper. Sinks, toilets, interior doors, etc. = 20-50% cheaper.
