It sounds like a famous pasar malam phrase in which sellers yell to lure customers. Not every buy-one-free-one stuff is a good bargain, but this one.. the one I gonna mention is certainly a good one!
Ta-daa! My FreshKon gift bag. 
They have a promotion recently--- buy 2 Free 1 for color fusion lens.Sounds tempting? No-no, coz' I got this at BUY 1 FREE 1 !!!
Look carefully at the specifications.
Previously they have only 9 colours, but now the NEW 4 are awesome ;D
It is RM70 per pair in every optic centre you go, but last week I get it at only RM70 for TWO pairs!
Meaning only 35 bucks per month, not bad eh?
I chose brilliant brown. Hope it looks nice ;X
And I’ve gotten mine too ;D
Thanks FreshKon and Focus Point for the great deal!
