Wal-Mart

I have a general question for the masses.
Not sure if any of you ever buy clothes at Wal-Mart but today I was there and I found two tops I really liked and when I went to buy them I was actually denied the sale. I asked the cashier why and she said they were on "recall" and that Wal-Mart wouldn't sell them.
I have never heard of this, she said her opinion was they were made in China and the dye on the fabric was probably bad.
Has this happened to anyone ever.?
I am totally serious, this really happened today while there in Fishkill.
