Hello! What's your name, and how may I help you today?
I was looking at some boots yesterday and price was a lot lower than today.  Why?
Let me check that for you.

May I verify your identity to find this out? I would just need your full name, Order ID and Account ID.

Our prices often change according to our algorithm, and there is nothing we can do to change that according to our policy. It could be the algorithm decided to change it due to time, season, etc.
Well I'm not happy paying more today than I would have yesterday
I understand entirely. Here, for the unexpected change let me offer you a discount code.

I would much rather have a refund of the price difference.  It's only fair
I see, how much was the price difference between today and yesterday?
$9
I have changed your order to meet the price-difference.
Thank you.  So my credit card only shows $85 charge now?
It should be updated to do so, yes.
I appreciate it. Thanks for being so nice
No problem, thank you. Anything else I can help you with today?
That's all thanks.
Have a great day!\
