there's no canned soups
I've not seen any for at least a decade in PL, and even then, only rarely (apart from when M&S were there, however their products aren't Polish). Tinned fruit is rare, though it does exist. Plenty of frozen, dried, and bottled. Of the packet soups on that website, only the barszcz is any good (and best avoid the instant one).
The pasztet (potted meat; they call it pie on the website) is fairly standard; worth trying, though that isn't a particularly interesting brand.
Looking at the stuff on the website, it isn't a very inspiring collecrion, however it represents pretty well much of what you'd find in a small and not very good grocer's shop.
The preserves are probably the best bit of that site. Łowicz is an ok brand, made in the town of that name (when I was a kid, we always had Krakus which is good). The first one on the list is translated there as 'plum jam'. It isn't jam, it's powidło, rather different to jam, and I recommend it. It's a more sophisticated product, darker and less sweet than plum jam and with a slightly smokey, pruney taste. Home made is the best, however the jar on the website is fine.
