A cheaper and lesser alternative to Berocca, $0.1625 it's almost half the price as the recent Berocca deal for $0.28-$0.30/Tablet but the doses are generally much less (from a quick cross reference I did) so do your research and comparison before you purchase. The voost energy tablets also contain guranna which Berocca don't contain, if you don't want guranna then there is a regular Multivitamin product.
These are $2.99/10pk, $4.99/20pk or $12.99/60pk at Chemist Warehouse for comparison.
