Yes, I saw the article. And, in general, I quite agreed with it. I first found Heyer's Regencies when I was still living in NYC. I read them all, many of them bought though some from the Library. And I moved those I'd bought to California, where they got read again. But didn't move them to Canada.
But then, several years ago, there were massive sales on pretty much all of her books, at $1.99. Just when there were also 90% coupons for Kobo. I bought literally every single Heyer I could find, and finished off the list the following year when Amazon had then at $1.99 again.
These days, I parse them out, hoarding them in my TBR, but avoiding splurging on them.
