Once is a mistake. Twice is... me in the wrong?

So despite my grumbling about Harper collins, they do publish a nice wealth of 'romances in the regency period', including those by Stephanie Laurens, whose new book To Distraction is due out next Tuesday.
The one redeeming quality of the Harper Collins website is that, when it takes their fancy, they supply a 3-chapter taster of their ebooks - including this latest release, although they have the link wrong because the free sample is really available through this link and not the one they supply.

Anyhow. Thing is. I downloaded and read the sample chapters. And was struck by...
apostrophised plurals. No, I don't know what I mean either; but surely the appreviation of "there are" is "there're" and not "there's" ?

I mean, is a sentence like this:

“There’s the social obligations, of course.”
(To Distraction, page 13)

...or this:

“I’m sure you’ll find plenty to interest you during the next few days. Maria usually organizes a picnic on the downs, and there’s some lovely rides.”
(To Distraction, page 21)

..correct?
Because, in my ignorance, I'd have said that they both should have been the result of "there are", not "there is"

And If I'm right, what's happening to Harper Collin's copy editors (is that the right phrase?)? This, on top of the ebooks cover disgrace, really does make me wonder...
