Guess, it's for more busy large cities where people don't have time for shopping :)
I was surprised to find 10 different companies in the UK which offer this , didn't even know this type of service existed until I saw your post. Germany has them too, but nothing at all for Poland. Having said that, I couldn't find anything for Moscow either, and as you've used them there, maybe Poland has them, but I just can't find them!
