[quote name='MIX_MASTER_ICE']So Wal-Mart made a mistake and you returned something you didn't order to get more money. I didn't realize dishonesty was acceptable when a mistake is made.[/QUOTE]
Here's what would happen at my local Walmart:
Me: Hi, I ordered this Video Game and instead got this *shows lady e-Pen thing*.
Her: Um, hold on let me get a manager.
*10 minutes later manager shows up*
Me: Hi, I placed an order on Walmart.com and they sent me the wrong item.
Manager: *Takes a look at receipt and the item* This isn't what you ordered.
Me: Yes, I know, they sent me the wrong item.
Manager: You'll have to speak with someone from Walmart.com. We can't do anything about it here because you didn't purchase it from this store. *Hands me back receipt and item* *Walks away*
Me: *Drives home and makes call*
Phone: Due to longer than average hold times, we expect your call to be answered in 27 minutes; please stay on the line.
Me: *sigh*
*30 minutes later*
Me: Hello?
Phone: Hello Sir! My name is Goobra, how can I help you today?
Me: *Explains situation"
Goobra: Oh, yes sir, we are very sorry to hear about this! Unfortunately because it was an error on the site's side, we will need you to mail back the item to one of our shipping facilities, once we get the item we will return your original purchase cost within 14 business days!
Me: I don't want to pay for shipping and what will happen to the shipping I already paid?
Goobra: Unfortunately we do not cover shipping costs on return items.
Me: *Getting a little mad now*
Goobra: You have a nice day sir! *hangs up*
Me: *Drives up to the next Walmart and returns it there*
Edit:
If I saw someone drop a $20 bill on the ground, I would stop them and return it.
If I accidentally walked out of the store with something I didn't buy, I'd go back in and give it back.
Dealing with Walmart, much less in a situation like this, just IS NOT WORTH IT.
