I just picked up a large collection of books, which includes a large assortment of Doctor Who Past Doctor Adventures books.
I don't have time to take photos of all of the books, but most of them are in great used or even like-new condition. I have attached a photo of a representative sample. I will also list obvious issues below on individual books. Some of these have seller labels on them.

** THIS AUCTION INCLUDES THE "PAST DOCTOR ADVENTURES" BOOKS, MOSTLY FEATURING DOCTORS 1 THROUGH 7 **
** PLUS 2 COPIES OF THE UNFOLDING TEXT IN RATHER POOR CONDITION **

These are a little pricier than the novelisations for the original series, but generally cheaper than the New Adventures books, although some near the end of the series get a little pricey.  Unfortunately I do not have all (or most) of the books like I did with the older series, as the person I got this collection from apparently stopped buying the books around 2001.

I have listed these at around what others are listing them for, but I'm also giving a significantly bigger discount on quantities of 2 or more than I did on the original series books, so hopefully I'll have the best deals overall!  NOTE - if you pick up one of the more-expensive books, you might want to grab a couple of the cheaper ones, since with the multli-book discount, you may effectively be getting the cheaper ones for free!

I have listed the auction's condition as "acceptable", but most of them look like they have not been read. Feel free to ask for pictures of any of the books!  Note that a lot of these after the first 1/3 of the run have a "bumpy" cover near the spine on either the front or the back, as if Virgin Books was having problems in their assembly process.  They generally aren't creased, but definitely bumpy to the touch.

The following books have significant defects (prices have been lowered compared to normal accordingly):

I will be listing these in multiple "you-pick" auctions; please add $5 shipping for media mail plus 20c for each additional book up to a maximum of $10.

NOTE: If you purchase books from multiple auctions, please wait for me to send a "combined" invoice so you don't pay the $5 base on each auction and can take advantage of the maximum, if you really want to add to your collection! I've also added a discount for 4 or more books; I don't know how eBay combines these over multiple auctions, but we can figure something out if we need to, so you get the discount on all books over multiple auctions.
