Thank you for contacting Acme.  How may I help you today?
I was looking at your website and there were several items I would like to purchase.  Can you explain the different membership levels to me?
Of course, let me just pull up some information from our files
okay, great
We offer bronze, silver, and gold membership levels, which all come with rewards for customers all members, of any level, receive an invitation to our annual holiday extravaganza Bronze members save on shipping fees and get promo codes.  Silver members get all of that plus unlimited cancellations at any time.  And finally, Gold members also get unlimited refunds that will always be given, no questions asked
and what is the price difference for each level/
Those are actually based on your purchase history
And does any level receive free shipping?
at various levels we will contact you with your new membership status, so it pays to be a repeat shopper They don't offer free shipping at point of purchase, but Gold and Silver may allow you to add an item to an order that has already shipped, and that would come with no additional charges
Oh, I think I understand now.  So the more you spend the higher your membership status, right?
Yes, that's right

Are there any other questions that I can help you with today?
Oh okay, that's very interesting .  Thank you for your help.  I will take some time to look at the website for things I might need.  No other help needed.  Thanks, and have a good day.
You're welcome, and have a good day, too
