Having gotten bored with no Kobo coupons to speak of recently, I decided to go traveling...
(Note: for links to show these editions you need to already be in the Kobo India store)
If you are able to travel to India, here are some interesting mystery finds (to me, at least):
Robert Barnard - seven titles under R 101, which corresponds to about Us $1.50, with three at about $0.75. Some of these have been inexpensive for a while, but four were new to me as inexpensive titles in India. Kindle US prices on three of those four were all over $10.

A gazillion (very technical term

) titles by George Harmon Coxe for R 142 (a few) to R 161 (the rest) - approx US $2.10 - $2.40. These range from $4.61 to $5.99 at Kindle US.

I think someone mentioned these before quite a while ago, but...
There are two omnibi of Travis McGee books by John D MacDonald - books 1-3 and books 4-6. These are R 440 each, which works out to about US $6.60 for each set of three titles, or $2.20 per book if you need all three in the set. The individual Travis McGee titles range from R 279 to R 315, or about US $4.20 to $4.70. These are more expensive, but still way better than the $11.99 for most individual titles at Kindle US. There are also a bunch of other inexpensive non-series titles for R 101 (approx US $1.50) or less, such as
Bullet for Cinderella (which is inexpensive pretty much everywhere),
Clemmie,
Judge Me Not,
All Those Condemned,
The Empty Trap,
Weep for Me and a bunch of others. I've had trouble getting a "clean" link for all of these, but if you poke around, you can find a bunch. The link below is for the Travis McGee titles.

Similarly for the Inspector Lynley books by Elizabeth George, there is an omnibus of titles 1 - 4 for R 608, or about US $9.10 (approx $2.25 each if you need all four), and then individual titles range from R 297 to R 344 (except the newest title), or about US $4.45 to $5.15. Expensive, but still a lot less than Kindle US prices, mostly ranging from $8 to $12.

(Again, I have some vague memory that someone might have mentioned this a loooong time ago...) A bunch of Elizabeth Peters titles at R 212 (about US $3.20) and some for more. There are multiple editions of many at different prices so look carefully before you buy. The Amelia Peabody series tends to range $9 - $10 at Kindle US; other series, such as Vicky Bliss (actually my favorite) and Jacqueline Kirby tend to be less expensive, so check carefully.

Anyway, I guess I'm not bored anymore...
Oh yeah, and I had no trouble checking out in Kobo India with my normal no-int'l-fee credit card (a MasterCard).
