Some of the later titles in Kate Sedley’s Roger the Chapman historical series have gone on sale reasonably often, but not the earlier ones. Now it seems as if Sedley may have gotten back the rights to some of the earlier titles, since the first five books are recently out (2021) in e-book editions from Canelo.
And right now, the first in the series, Death and the Chapman, is on sale for $0.99/£0.99 in the US/UK, and also discountable at Kobo (recent code, “Partners22”, for 40% off, works).
The other four are also reasonably priced at £1.99 each at Kindle UK, $2.99 each at Kindle US, and $3.99 each at Kobo US.
BUT…if you use the “Partners22” code at Kobo, they are 2.39 each there, and if you have Kobo VIP, which stacks with the code, they are $2.15 each. Remember though, you have to put them one-at-a-time in the cart, and check out separately for each one, since “Partners22” is multi-use, but only once per cart.
And here are series links for all five…
