Travel / Open Markets in Poland to buy stuff - where are they? [10]

What are some good open markets??

I would like to buy things like:
fruits/veggies
fresh eggs
fresh milk
home decor

I know Poland is a word of mouth country... so where are these little gems hidden?

Life / Online Shopping in Poland - Any websites where I can get brand names for a discount online? [7]

Hi,

I just moved to Poland. I will be here for two years.

Back at home I usually do all my shopping online because I enjoy the discounts. I use sites like RueLaLa and Hautelook. Is there anything similar to that in Poland? I would like an online site.

Also, I live in Warsaw, so I have been going to T.K. Maxx -- are there any other stores like that in Warsaw?

Thanks!
