When am I paid royalties? When do quarters start and end?

We pay royalties on a quarterly basis:
First Quarter: 1 January to 31 March (cheques are mailed in late May)
Second Quarter: 1 April to 30 June (cheques mailed in late August)
Third Quarter: 1 July to 30 September (cheques mailed in late November)
Fourth Quarter: 1 October to 31 December (cheques mailed in late February)

You are paid for the books sold and shipped in the given time frame. If a book was purchased online on 30 March, but the book was not actually printed and shipped until 2 April, then you would be paid in the second quarter, not the first, since the book wasn’t shipped until the second quarter.

You will only be paid once for the original book sale. For instance, if a book is resold in any kind of second-hand store, you will not earn a royalty on the purchase. Also, you earn a royalty when a retailer purchases your printed book for their store, but not when a consumer actually purchases your book off the shelf.
