On Tuesday http://vyrso.com/products/search?q=&unlocked=no&start=&sort=pricelo&pageSize=60 showed 3 free books, right now it shows the same 3 free books, yet yesterday there was none. I assumed then that the offers expired on the 28th (I had noticed that the free ones on http://vyrso.com/february?utm_source=vyrso&utm_medium=homepageslide&utm_content=slide_2&utm_campaign=februarysale did), but since they're back again today it looks like the code has a problem with 29 days in February.
I think we can safely assume, though, that this is one bug no one will complain if you don't fix in a hurry. I just thought you should know.
