Thank you for contacting AcmeBrands. How can I help you today?
Yes, I'm trying to buy a pair of boots, but my cart won't update.
Can you try to refresh the page and add the item again?
That didn't help.
OK - can you try to log out and log back in?
I'll try It's still not working.
Can you check to make sure the item isn't out of stock?  This will be on the bottom left corner of the product page.
Okay, let me check... Yup, it's out of stock.
I do apologize about that, but check back on our site frequently as we receive new shipments daily. Is there anything else I can help with today?
Okay, I will.  That will be all. Thank you.
Thank you, have a great day!
