Use coupon code FAVFA - prices won't be discounted until check-out.
It works for multiple books, although the headline looks like it's for a single book.
FYI: Looks like ordering multiple books created issues getting delivery of yesterday's purchases. I also lost the discount after checkout. Today's order pricing isn't what was reflected at checkout.
Today the two titles I bought in two orders are listed as "registered" under the registered books area.
Order status on both orders reflects "BOOKED", but shipped is 0, download link is not active, and the books are not listed in the downloads section.
One purchase shows the discount, the other reflects full price without discount.
An email to O'Reilly auto-responded with this:
> Thank you for contacting O'Reilly Media Customer Service. We are experiencing a very heavy volume of orders due to our recent promotion. This is affecting the delivery and access of your electronic media. Please be patient and keep checking your account.
TL;DR: Buyers should double-check orders to see what was actually charged.
I apologize for the delay in getting back to you. I checked your account and you now have access. You can download your ebook here:
There were issues with our servers on Friday due to high loads, and we've been working to make sure everyone received the content they purchased.
We have refunded you the amount that you would have saved if the discount code was applied to one of your orders. Please allow 5-7 business days for the credit to appear on your statement.
Thank you again for your orders and for your understanding. Please let us know if we can be of any further assistance.
