@ljwrites huh i was able to get all ten books at once without issue a few days ago, i wonder what changed
@Satsuma Yeah it was weird, I got a message that I could only have one at a time. Maybe the message was some kind of fluke or error and if I'd just clicked through to checkout without making a donation it would have worked anyway? 
@Satsuma I don't remember doing so, but it could be that my browsing experience is atypical because I have images turned off by default. I think I'll delete the post since the sale should be over anyway.
