On most plans, you can post up to eight books at a time in an envelope. This is called a swap. If you return fewer than eight books, you might not be making the most of your allocated number of swaps allowed in a month (if you send four books back to us, we’ll post four new ones out — but you could have had eight!).
Please don’t post more than eight books in one go, as it’s likely that they won’t fit in the envelopes we use and won’t make it back to us.
If you’re on our “Extended” band, we’ll be sending you six books instead of eight (because they’re much larger and longer!). Please just send back up to six books when you’re on this band.
