If something I used in the store here, I most give the credit if I can remember at once from whom this product was. If I have enough power, I take a look in the store from whom this product was but if I´m too tired...next time ;-)
I do this becourse I know that the vendors have their own top-list of "most credited vendors", so I do it for them. If a product is from another store, I don´t mention it here.
I think that we all know the latest fashion or characters from all urgent stores on web.
If someone wants to know what I have used, he/she can feel free to ask me. I´ll have a look on it than.
