Bargain @ $2.99 and up for today only (May 15th) as part of the Kindle Daily Deal in Canada & the US (apparently exclusive, but you can price-match at Kobo):
Assorted DIY hobby learning titles in Wiley's Dummies series, including a number of rather nice language learning and musical education books (mostly at the $4.99-$6.99 range).
For language-learning hobbyists, @ $6.99 each in the
All In One For Dummies series which are omnibus editions of a number of previous learning/grammar/vocabulary books are available for German, Italian, Spanish, and French (covering French-Canadian, at least of the Quebec variety, which is moderately unusual for anglophone learning materials
). For comparison purposes, they're regularly priced at $27.99 CAD at Kobo.
And at $4.99 there's
Japanese for Dummies. These all come with downloadable supplementary audiofiles. The ones for the Italian AIO book you can get directly from the website linked in the beginning of the text. The ones for the other titles you have to hoop jump a little for, by visiting their
Wiley Booksupport site and enter either the ISBN or the book title and wait for the search results to pop up your title and click on it to select and download the zip files (don't try to fill in all 3 fields with accurate information, or you will get no search results). NB: some of them are very large files at hundreds of mb, and they advise you to download via a stable connection from your desktop computer.
There's also some DIY books for learning banjo, guitar, classical music appreciation, violin, regular and blues harmonica (sold separately), piano, mandolin, and also some computer programming and job help stuff.
Linkage for the lot @
Amazon main &
CA, if you're interested.
While I personally wouldn't consider the Dummies books to be in the top tier of DIY language learning materials, they seem to be fairly decently-done and offer solid basics for beginners with a few nice extras that might help one advance to a more intermediate level, and I've no hesitation whatsoever about scooping these up myself, at these low prices.
