Went to purchase a 55 inch TV. The clerk couldn't answer any questions about the different brands. Took someone with me to put the TV in my car. He asked her if it would be OK to leave the TV at the store till he could get his truck to pick it up. She said NO. Once I purchased it the TV was no longer Wal-Mart's responsibility if I left it to arrange for pick up. I was paying cash. Left the TV there. How incredibly frustrating and what an ignorant clerk.
