Tefl can be bought for around $40 for 160 hours course on groupon

And for a lot of schools and programmes, this is (unfortunately) sufficient. If you're only going to teach for a year or two, you won't have time to develop any real teaching skills anyway, so there's perhaps not much point in forking out 1000+ for a certificate or diploma course.

I still recommend the CELTA as the gold standard for teaching English if you value pedagogy and teaching as a profession, but outside of Europe and Australia, its not quite as well appreciated as it perhaps should be.
If you've not the time or inclination for the CELTA, this might be a decent alternative. Being able to use this towards a Master of TESOL later on so is a major plus.
